What are the main function of a forensic chemist?

Forensic chemists analyze non-biological trace evidence found at crime scenes in order to identify unknown materials and match samples to known substances. They also analyze drugs/controlled substances taken from scenes and people in order to identify and sometimes quantify these materials.

What are the two types of tests conducted by a forensic chemist?

There are two main types of tests used to determine whether an illegal drug is present in a substance: presumptive tests and confirmatory tests. Presumptive tests are less precise and indicate that an illegal substance may be present. Confirmatory tests provide a positive identification of the substance in question.

Does Luminol destroy DNA?

Our findings indicated that luminol had no destructive effect on species tests as well as on elution method for the detection of blood group antigens and does not have an adverse effect on subsequent DNA typing using PCR.
