Performs analysis on trace evidence includes fibers, resins, paints, and different types of foreign materials related to various cases such as murder, robbery, theft, crash, etc.. Analysis of trace evidence is performed by infrared spectroscopy (FT-IR), microspectrophotometry(MSP), Raman spectroscopy, and X-ray fluorescence spectroscopy (XRF), X-ray diffractometer (XRD) with various microscopes (stereoscopic microscope, high magnification microscope, polarizing light microscope, etc.).

Determines a source of origin and performs comparison of questioned materials to known materials based on chemical fingerprints of substances by the stable isotope ratio and multi-elemental analyses. Trace elements and isotope composition of materials vary depending on a source of origin and raw materials used for manufacturing products. Chemical fingerprint analysis is performed using the-state-of-the-art instrument (LA-ICP-MS, IRMS, XRF, XRD, etc.) to determine a source of origin and to perform comparison of questioned materials to known materials such as paint chips, tape, glass fragments, and so on. The laboratory has established a database of glass, soil, tape, etc. to achieve goals by the stable isotopes and multi-elemental analyses.

Conducts the analysis of biological evidences in the case of driving under the influence of alcohol(DUIA), sexual assault cases, and alcohol/disease related death cases. The lab confirms the alcohol concentration and measures the content related to decomposition index substances and drinking in blood and other tissues of postmortem specimens performing ketone analysis, which is an index substance for chronic alcoholism and diabetes. Recently, the lab has developed a new method to determine the consumption of alcohol analyzing the ethanol metabolites(EtG and EtS) from blood and urine samples.

Determines the presence and concentration of various hazardous chemical substances, including heavy metals and acids in water, soil and waste in different forensic environmental cases. In addition, the lab performs the analysis of chemical agent components from biological samples, related to leak, spraying, suicide, homicide, and poisoning cases including misuse and abuse, etc..

Analyzes ignitable liquids from fire debris to determine whether ignitable liquids are related to the case. Also, the lab analyzes and evaluates the authenticity of oil in fraud oil cases, potential materials for chemical accidents, and hazardous gases in accidental poisoning or suicide cases.
