Personal tape sampler

Another sensor system that further expands the capabilities of the Chronotox is the Personal Tape Sampler (PTS). The PTS (Figure 5) is a miniaturized gas monitor designed primarily to be worn by a worker during his entire workshift. It operates on the principle of specific chemical colorimetric reactions occurring on a dry chemically impregnated paper tape and gives... 

The PTS uses the principle of a specific colorimetric reaction, each toxic substance being detected by a reaction system specific to that gas. This principle provides the capability for extreme sensitivity down to less than one part per billion (10 ) while maintaining excellent specificity. Reactive chemicals are impregnated onto a continuous paper tape by a special process producing a dry reaction system. The tape is put into cassettes for convenient use and replacement in the Personal Tape Sampler (PTS).
