Abstract
Abstract The use of hazardous hydride gases in modern research and production has generated a need for quick analysis of ambient air for threshold limit value (TLV) levels of hydride gases. In general, the systems available today that satisfy this need fall into two categories. These are systems that are very fast to react but do not identify the hydride and systems that do identify the hydride but take several minutes to complete the analysis. These two different approaches to the problem are examined here; each has its own strengths in different applications. The first system is made by MDA Scientific and has been applied to a research environment. Lessons have been learned regarding the importance of system features and placement strategies. The second system is composed of a standard laboratory gas chromatograph utilizing a photo-ionization detector and a convenient sampling system.
