Abstract: A chemical sample collection and detection system is disclosed. The chemical sample collection and detection system includes a sample collection device and a detection device. The sample collection device includes a housing having two opposite sides and at least one openings on each side to allow a fluid sample passing through the housing; and a sorbent material placed between the two opposite sides of the housing or a sorbent coated screen. The sorbent material adsorbs chemical vapors, and traps particles and aerosols in the fluid sample when the fluid sample passes the housing through the openings. The detection device includes an atmospheric pressure ionization source and an ion detector. The atmospheric pressure ionization source desorbs and ionizes the chemicals trapped/sorbed on the sorbent material and the ion detector analyzes the ions for the presence of the sorbed chemical.

Abstract: Systems and methods are provided for collecting and analyzing analytes. One embodiment of the invention includes a system for collecting analyte. The system comprises a sampling section disposed on a collection platform and an air source that provides an analyte to be sorbed by the sampling section.

Abstract: A chemical detection system is disclosed. The chemical detection system includes an atmospheric pressure ionization (API) source that produces an API stream, a sample delivery system that delivers a liquid sample in a continuous manner to the API stream, an ion detector capable of detecting a molecule of interest and a control device. Also disclosed is a method for detecting a chemical of interest in a liquid sample.
