    摘要: A chemical agent detection system is provided that includes a fluid sampling collector suitable for the collecting, concentrating, filtering and storing of chemical agents. Preferably a solid phase extraction syringe is coupled to an adaptor via an injection port. The adaptor forms an outer surface of a sample containment reservoir that allows the fluid sampling collector to associate with a chemical agent detector such as the M256A2 chemical agent detector. The inventive chemical agent detection system allows rapid, low level on-site detection of chemical agents such as nerve agents in fluid media.

    摘要: A device for use with a detection means and a solvent source for sampling low volatility hazardous chemicals within a sample matrix is comprised of a sonicator having a probe for providing mechanical agitation to the sample matrix; means for transporting solvent gas from the solvent source to the sample matrix; means for transporting sample gas from the sample matrix to the detection means; and a heating element for heating the sample gas, solvent gas, and sample matrix. The device may include a thermocouple for providing a temperature reading. It also may include a plurality of interchangeable probe tips of different shapes.
