Improvements in the Monitoring of ppm Level Organic Vapors with Field Portable Instruments.
NIOSH 1991 Feb:483-496
The use of field portable instruments for monitoring organic vapors at the parts per million level was discussed. It was estimated that there are about 1250 organic compounds in general use which require organic vapor monitoring. About 96% of these should be listed as toxic or potentially toxic and thus there may be a need for toxic level monitoring. This group of compounds was by far the most numerous family of substances for which specific monitoring would be needed. The range of toxic concentrations usually was from 0.1 to 1000 parts per million with only very small numbers outside this range. Methods suitable for portable direct reading monitors included closed path infrared absorption, flame ionization detector (FID), gas chromatography with FID, catalytic oxidation, photoionization detector (PID), and gas chromatography with PID. A general description of PID based instruments was presented, along with special features of PID based instruments and PID gas chromatography improvements.
