Law Enforcement

The ability to collect and analyze gas phase samples for trace chemicals has many uses in forensic science. Some of the applications include:

● Illegal Drug Laboratories
① Indoor Air Quality testing during cleanup
② Locate chemical signature from “cooking” process
③ Identify presence of chemical signature in breath (for health risk determination and forensics)
④ Chemical signature on clothing via direct thermal desorption in Large Volume Headspace (LVH) vials.

● Detection of Drugs of Abuse (or their metabolic breakdown products in breath)

● Arson Investigation

● Detection of hidden chemicals (in vehicles or warehouses from trace vapor pressure signature)

Breath Analysis

Analysis of volatile chemicals in breath can be used to determine the extent of exposure, which finds applications in both industrial hygiene and forensic science. Measuring and comparing relative abundances of chemicals produced in the human body can also help to screen for many metabolic disorders and diseases.

The economical 39-82000 Breath Sampler allows non-equilibrated bronchial air to be first eliminated before collecting the deeper, alveolar air which is more representative of levels of chemicals in the blood.Conversely, collecting air using shallow, rapid breathing allows chemicals in the mouth to be sampled when studying oral hygiene or avor changes during food consumption (aftertaste).
