Gas Chromatograph (GC)

The Drug Chemistry Section of the Crime Laboratory consists of a Section Supervisor and four Forensic Scientists who are responsible for examining the following types of evidence:

  • Analysis of samples to determine the possible presence of controlled substances utilizing functional group chemical color tests, GC, GC/MS, and FTIR. These samples may include solid and liquid pharmaceuticals, plant material, powders, and liquids (syringe rinses, clandestine laboratory samples, and tampered drinks).
  • Quantitative (purity) analysis of methamphetamine for federal prosecution.

Crime Laboratory Syringe Submission/Testing Guidelines

Submission guidelines:

  • It is not acceptable to submit ANY hypodermic syringes to the NSP Crime Laboratory, with the exception of the screw off needle type with the needle entirely removed by unscrewing it from the syringe. It is NOT acceptable to "clip" off a needle.
  • Any syringe received in the laboratory which is not of the screw off needle type will be returned to the submitting agency along with any evidence packaged with it.

  • Although NOT recommended due to the extreme health risk involved (make sure to consult the testing guidelines prior to doing this):
    • If a syringe has liquid in it, the liquid may be placed in a clean vial (red topped vacutainer tubes from a phlebotomy lab are recommended). The vial should be sealed and labeled as a biohazard.
    • If the syringe contains no liquid, it is acceptable to rinse through it with as SMALL amount rubbing alcohol (water if alcohol is not available). Using large volumes of liquid dilutes the sample and makes analysis difficult. Place this liquid rinse in a vial as described above and submit it to the laboratory.

Testing guidelines:

  • Correctly submitted syringe liquids will ONLY be tested if:
    • They are the only evidence in the case.
    • The syringe was the probable cause for the search and this is CLEARLY INDICATED on the submittal form.
    • Prosecution provides other acceptable justification directly to the laboratory.
