The work involves responsibility for performing chemical tests and analyses in the evaluation of physical evidence. Under the technical supervision of the Toxicologist, Center for Forensic Science, with administrative direction from the Director of Laboratories, an employee in this class performs chemical examinations of blood, tissue and body organs to detect presence and nature of toxic substances. The Forensic Chemist II is distinguished from the Forensic Chemist I by its responsibility for providing guidance to less experienced chemists and the ability to perform the more technical and complex procedures required in scientific analysis of physical evidence. An employee in this class typically reduces conclusions and findings to writing in the form of reports and appears as an expert witness during litigation. An employee in this class sets up, operates and maintains a variety of scientific instruments in performing chemical analyses. Does related work as required.




Validation and performance of specialized testing procedures for the analysis of various drugs in biological specimens.

Certifies data for DWI, probation urine drug screen and forensic toxicology analysis.

Sets up, operates, maintains and trains others in the use of scientific instruments used in analyses, such as infrared and ultraviolet spectrophotometers, liquid and gas chromatographs, mass spectrometers and related computer equipment for instrumental analysis of various materials.

Determines methods of analysis to be applied by Forensic Chemists I and supervises the work of the latter through review of findings and standards of investigation.

Trains Forensic Chemists I in technical procedures, handling of evidence and preparation of material for court testimony.

Trains law enforcement personnel and others responsible for gathering evidence.

Composes technical reports to convey findings of chemical analyses, inclusive of identity, quantity and comparison of physical evidence.
