Abstract

A detector apparatus is provided and includes a collector having access to a sample of a gaseous fluid and a tester coupled to and disposed remotely from the collector. The tester includes a test chamber into which a sample is directed from the collector, an excitation element to excite the sample in the test chamber and a spectrum analyzing device coupled to the test chamber to analyze the excited sample for evidence of a concentration of particles of interest in the gaseous fluid exceeding a threshold concentration. The threshold concentration is defined in accordance with a type of the particles of interest and a residence time of the sample.
