A method and system for detecting the presence of chemical and/or biological agents are disclosed. An additive, which may comprise a reactant and/or a catalyst selected for its capacity to react with, or to force a reaction involving a target chemical and/or biological agent, may be introduced into a sample of an ambient environment to be monitored. The additive may then react with the target agent, or, as a catalyst, may drive a reaction with the target agent, resulting in a reaction product that may be detected by one or more sensors or sensor arrays. The method and system may incorporate a plurality of sensor types in order to enhance the specificity of the method and system.

System and method for chemical and/or biological detection

There is provided a sample treatment apparatus which can, continuously and stably for a long time, treat a sample containing an easily precipitating substance such as sulfur and a measuring apparatus providing it. The sample treatment apparatus includes: a path for introducing a fluid for an aspirator, at least two sample flow paths A connected in one side to the path for introducing a fluid for an aspirator and connected in the other side to a sample collecting part, a sample flow path B connected in one side to one sample flow path A passing a fluid for an aspirator and connected in the other side to the other sample flow path A, a cooling part for cooling a part of the sample flow paths A, and a controller for selecting and switching the sample flow paths A into which a fluid for an aspirator is introduced.
