Product Overview

The Alcohol Quantitative Detection Analyzer — Blood/Urine/Saliva Micro-Sample, 20-300mg/100ml Wide Range, 10-Minute Rapid Quantification, ±10% Error High-Precision Body Fluid Alcohol Concentration Forensic Toxicological Analysis System (also referred to as the Alcohol Quantitative Detection Analyzer or Body Fluid Alcohol Concentration Tester) is a precision quantitative analysis instrument specifically designed for judicial forensic identification, criminal investigation, and traffic management departments. It constitutes a core alcohol quantitative detection equipment in the fields of forensic toxicological testing, traffic accident liability determination, and criminal forensic identification. This product is primarily used for the accurate quantitative determination of the internal alcohol content in the biological samples (such as blood, urine, and saliva) of parties involved, victims, especially those severely injured and comatose or deceased in cases (incidents). It fundamentally addresses the statutory evidence collection limitation of traditional breath alcohol testers, which cannot perform alcohol testing on individuals without spontaneous breathing capability, those severely injured and uncooperative, or deceased individuals. It provides legally valid scientific data support for determining the nature of the case, establishing accident liability, and advancing judicial procedures. The product features efficient detection performance: requiring only 1 milliliter of micro-sample and completing the entire process from sample preparation to quantitative analysis within 10 minutes. It covers the statutory blood alcohol concentration range from 20 to 300mg/100ml—spanning the legal thresholds for driving under the influence and drunk driving—with high precision and stability characterized by a relative error of ≤±10% and repeatability of ≤±5%. It perfectly adapts to various professional testing scenarios, including the judicial forensic identification of driver blood alcohol concentration in hit-and-run cases, objective assessment of the drinking status of involved parties in homicide and assault cases, evidentiary determination of alcohol-related violations in correctional facilities, and routine alcohol quantitative testing in forensic toxicology laboratories. It serves as a key judicial forensic technical equipment for ensuring the scientificity, fairness, and legal validity of alcohol-related fact determination in law enforcement and case handling.

Technical Principle

This instrument operates based on the principles of chemical analysis or biosensor quantitative detection technology. Through the selective recognition of ethanol molecules in the biological sample under test and the conversion of the concentration signal, it achieves the precise quantitative determination of alcohol content in micro-volume body fluid samples. In the sample preparation stage, the operator only needs to quantitatively transfer a 1 milliliter micro-sample from the blood, urine, or saliva specimen to be tested. After undergoing the necessary pre-treatment through the dedicated sample handling components, the sample is introduced into the instrument's detection unit via the sampler. The detection system built into the instrument undergoes a specific physicochemical reaction or bio-enzymatic catalytic reaction with the ethanol in the sample, generating a quantitative signal proportional to the alcohol concentration. After the signal undergoes high-precision analog-to-digital conversion and computation by the built-in microprocessor, the quantitative value of the alcohol content in the sample is directly output.

The entire testing process, from sample preparation to the output of the quantitative result, takes ≤10 minutes. The quantitative detection range covers 20 to 300mg/100ml, with a detection sensitivity of 20mg/100ml, completely encompassing all statutory criteria intervals for driving after drinking (≥20mg/100ml) and driving under intoxication (≥80mg/100ml) as stipulated in the national standard "Thresholds and Testing of Blood Alcohol Concentration for Vehicle Drivers." The analytical performance of the instrument has undergone rigorous methodological validation, with detection relative error controlled within ±10% and intra-batch repeatability of ≤±5%, meeting the stringent requirements of forensic identification for the precision of quantitative analytical methods. The system is equipped with calibrators and quality control materials, supporting standard curve calibration and quality control verification before and after each batch of testing, ensuring the consistency of test results under different times, different operators, and different sample matrix conditions. The instrument also supports the analysis and detection of ethanol content in environmental samples such as water samples, expanding the application scenarios for physical evidence traceability in alcohol-related cases. The entire unit adapts to AC 220V, 50Hz mains power supply, with an input power of 460VA and external dimensions of 600mm × 380mm × 300mm. Its compact structure makes it suitable for stable operation at a fixed workstation in a forensic toxicology laboratory.

Core Functions and Compliance Operational Value

Direct Body Fluid Quantitative Detection Capability for Special Individuals, Filling the Statutory Evidence Collection Gap of Breath Testing
The core advantage of this instrument lies in its ability to directly perform precise alcohol quantitative analysis on blood, urine, saliva and other biological body fluid samples. This characteristic breaks through the fundamental operational limitation of traditional breath alcohol testers, which must rely on the active, sustained expiratory cooperation of the subject to complete the test. It enables the objective determination of the internal alcohol content of individuals who are severely injured and comatose due to traffic accidents, those who cannot cooperate with a breath test due to craniocerebral injury or intoxication, and deceased accident parties or case victims. In the subsequent investigation of fatal hit-and-run traffic accident cases, performing a blood alcohol quantitative test on the blood of a deceased person who cannot breathe spontaneously provides the only obtainable objective biological evidence for determining whether the driver was under the influence of alcohol or intoxicated at the time of the accident. In major criminal cases such as homicide, the judicial forensic identification of the blood alcohol concentration of the deceased or injured provides critical technical evidence support for analyzing the cognitive and control capacities of the perpetrator at the time of the incident and assisting in determining the nature of the case. This special-individual detection capability extends the scope of alcohol evidence collection from those cooperating with breath tests to all individuals involved in the case, ensuring the comprehensiveness of alcohol-related fact determination within statutory procedures.

10-Minute Rapid Quantification and 20-300mg/100ml Wide Coverage, Supporting the Timeliness of Law Enforcement Case Handling and Statutory Threshold Criteria Requirements
The instrument requires only 1 milliliter of micro-sample, and the entire process from sample preparation to the output of quantitative results takes ≤10 minutes, significantly shortening the hours-long sample preparation and instrumental analysis cycle required by traditional gas chromatography alcohol testing. The detection sensitivity is 20mg/100ml, and the quantitative range covers 20 to 300mg/100ml, fully encompassing all criteria requirements from the minimum statutory threshold for driving under the influence (≥20mg/100ml) to the high-concentration range of severe intoxication. This wide-range rapid quantification capability enables case-handling agencies to obtain legally valid quantitative data support in a timely manner during the critical period when it is necessary to quickly obtain alcohol concentration evidence to decide whether to take criminal coercive measures against a suspect or continue detention for investigation. This avoids an evidence vacuum period caused by a prolonged testing cycle, fully responding, from the technical equipment level, to the statutory requirements for the timeliness of coercive measures in criminal case handling procedures.

Statutory Accuracy Standards and a Complete Quality Control System, Guaranteeing the Courtroom Admissibility and Judicial Credibility of Test Data
The instrument's detection relative error is ≤±10%, and its repeatability is ≤±5%. The analytical performance indicators meet the accuracy requirements of statutory alcohol quantitative testing. The system comes standard with calibrators and quality control materials, supporting the operation of standardized calibration and quality control procedures before, during, and after each batch of testing, ensuring that the test results are in a quality-controlled state. The quantitative data generated from each test, along with the corresponding calibration curves, quality control results, and operation logs, are automatically incorporated into the test report, forming a complete and traceable quality chain from the original sample to the final quantitative value. This standardized quality control system enables the alcohol quantitative test report to withstand procedural challenges from the defense regarding the accuracy of the testing method, the status of the instrument, and the standardization of the operating procedures during court cross-examination. It provides an objective evidentiary foundation that can withstand both legal and scientific scrutiny for drunk driving cases, DUI cases, traffic accident cases, and related criminal cases where alcohol concentration serves as the key basis for case determination.

Compliant Application Scenarios

Precise Blood Alcohol Concentration Determination Scenario in Traffic Accident Investigation and Liability Determination
In the investigation of traffic accidents involving casualties or significant property damage, the traffic management department lawfully collects blood samples from all involved drivers and uses this instrument to perform quantitative blood alcohol concentration testing. For drivers who are severely injured and comatose and cannot undergo breath testing, as well as for performing forensic toxicological testing on the blood of deceased accident victims, this instrument is the core equipment for obtaining the only objective evidence of internal alcohol content. The test results serve as the statutory basis for determining whether an accident party was involved in driving after drinking or driving under intoxication, providing key scientific evidence for the apportionment of accident liability, insurance claims, and the pursuit of criminal responsibility. The testing procedures and the use of results strictly comply with the statutory requirements of the Road Traffic Safety Law and the procedural regulations for public security organs handling drunk driving cases.

Judicial Forensic Identification Scenario for Personal Injury and Unnatural Death Criminal Cases
In the judicial forensic identification of criminal cases such as homicide, intentional injury causing death, and negligent homicide, the forensic pathologist performs a quantitative alcohol concentration test on the blood sample of the deceased or injured individual to analyze the drinking state of the concerned party at the time of the incident. The test results can serve as auxiliary reference for judging the cognitive ability, control capacity, and behavioral motivation of the perpetrator at the time of the incident, providing an objective forensic toxicology-level expert opinion for the court to correctly convict and sentence. The identification procedure complies with the normative requirements for forensic toxicology testing stipulated in the General Rules for Judicial Authentication Procedures.

Evidentiary Collection for Alcohol-Related Violations in Correctional Facilities and Drug Control & Public Order Management Scenario
In correctional facilities such as prisons, detention centers, custody houses, and compulsory isolated drug rehabilitation centers, blood or urine alcohol quantitative testing is performed on inmates or compulsory rehabilitation patients suspected of drinking, providing objective evidence for the determination of violations and subsequent punishment. In public order management and anti-drug law enforcement, body fluid alcohol content testing is performed on suspects of illegal activities such as alcohol-fueled affray or driving non-motor vehicles under the influence of alcohol, assisting in the determination of the illegal facts. The testing process strictly follows relevant law enforcement procedural regulations, safeguarding the lawful rights and interests of the individuals involved.

Core Technical Parameters

Regarding detection performance, the quantitative detection range covers 20 to 300mg/100ml, with a detection sensitivity of 20mg/100ml, completely encompassing the statutory criteria interval from driving under the influence to driving under intoxication. In terms of precision, the relative error is ≤±10%, and the repeatability is ≤±5%, meeting the stringent requirements of judicial forensic identification for the accuracy and stability of quantitative analytical methods. Regarding analysis speed, the testing time for a single sample is ≤10 minutes, with the entire process from sample preparation to the output of the quantitative result being completed within a short time frame. Applicable sample types include whole blood, urine, saliva, and water samples. The physical dimensions are approximately 600mm × 380mm × 300mm, featuring a compact structure. The standard configuration includes one Alcohol Quantitative Detection Analyzer main unit, one set of dedicated sample handling components and sampler, one set of calibrators and quality control materials, one set of data analysis and management software, and the necessary power and connecting cables.

Compliant Field Application Cases

A major traffic accident occurred in a city where a car struck a pedestrian and fled the scene, resulting in the death of the pedestrian. The traffic police brigade located a suspicious sedan in the early hours of the following day and summoned the registered owner of the vehicle, who was sleeping at home, to the public security organ. The suspect denied driving the vehicle at the time of the incident, claiming he had been drinking at home all night and had not gone out. Because the suspect was intoxicated and unable to undergo an effective breath test, the case handling officers, in accordance with statutory procedures, took him to a designated medical institution for the extraction of a venous blood sample. The blood sample was immediately sent to the criminal technical toxicology laboratory of the municipal public security bureau. The forensic examiner used this Alcohol Quantitative Detection Analyzer to perform a quantitative analysis on the blood sample, obtaining a test result of a blood alcohol concentration of 185mg/100ml within 10 minutes. During the subsequent interrogation, the investigators, combining the surveillance footage from the accident scene, the vehicle trajectory analysis, and the quantitative evidence of the blood alcohol concentration, broke through the suspect's psychological defenses. The suspect eventually confessed to the entire sequence of events of driving under the influence, causing the accident, and fleeing. In this case, the rapid and accurate detection of the blood sample of the intoxicated suspect by the Alcohol Quantitative Detection Analyzer provided decisive technical support for the timely preservation of critical evidence and for breaking the deadlock of the zero-confession situation.

A forensic identification center accepted a commission to perform a forensic examination in a case involving a suspected serious intentional injury committed under the influence of alcohol. The examinee was a middle-aged male who had fallen into a coma due to a craniocerebral injury following the incident and was unable to cooperate with a breath alcohol test. In accordance with the norms for forensic clinical and toxicological examination, the forensic examiner used this instrument to perform a quantitative alcohol concentration test on the blood sample retained from the examinee at the time of admission, obtaining forensic identification data indicating a blood alcohol concentration of 156mg/100ml. Based on this quantitative result, combined with the clinical manifestations recorded in the medical records, the examiner issued a judicial forensic expert opinion stating that the examinee was in an intoxicated state at the time of the incident. This expert opinion was admitted during the court proceedings, providing objective toxicological evidence for the judge to determine whether the defendant's capacity for recognition and control was diminished due to alcohol intoxication at the time of the incident. The judgment on the criminal incidental civil compensation portion of the case was thus provided with a sufficient factual basis.
