Abstract
Abstract Failure to recognize two basic types of air leakage, external and by-pass, with commercial and custom-made sampling filter holders may lead to serious sampling errors. Simple methods for static testing of these devices are discussed for negative and positive pressure operation. Construction details are provided for a filter paper holder which, with conventional sampling media, i.e., membrane filters and all-glass papers, permits essentially leakproof performance.
