A validation procedure for air sampling-analysis systems.
Validation of solid sorbent air sampling-analytical systems used to evaluate employee exposures to substances in the work place air is a fundamental part of any industrial hygiene air sampling program. In April, 1977, the National Institute for Occupational Safety and Health (NIOSH) published "Documentation of the NIOSH Validation tests", as part of the Standards Completion Project. This paper presents an alternative validation procedure which is more easily understood, is more rigorous, and provides for greater accuracy and precision.

A quality control program for analytical procedures using standard additions.
A technique is presented which permits the rapid, simple quality control of analyses that are calibrated by the method of standard additions. The control program is based on the recovery of known amounts of added-in standard material, rather than the direct reading of instrument response.
