Trace
evidence is generally defined as physical evidence that results
from the transfer of small quantities of materials like hair,
textile fibers, paint chips, and glass fragments. In addition
to these classic trace evidence samples the San Diego Sheriff's
Lab Trace Analysis Unit examines fire debris, explosives,
and soil as well as impressions of foot wear and tires. The
analytical techniques used for trace evidence combine classic
undergraduate level chemistry with microscopy (stereo, polarized
light, and electron) and instrumentation like GCMS, FTIR,
capillary electrophoresis, and pyrolysis gas chromatography.
A trace
section intern is required to be someone who either has or
is working towards a bachelor's degree in a hard science like
chemistry, biochemistry, biology, criminalistics, or related
science focus and have an understanding of basic chemical
principles and instrumental theory. He or she must be willing
to independently work on a trace related project like an instrumental
or analytical procedure validation, sample library building,
or research.
