The comparison of detectors for gas chromatography

Abstract

Abstract The properties of gas chromatography detectors are considered under the main headings (1) detector sensitivity, (2) response time, (3) the relationship of detector output to molecular parameters and (4) the ease of construction and operation of detectors. In particular, the use of gas concentration units (μg./ml.) for the specification of detector sensitivity is advocated. Detector response time is considered in some detail because of its importance for work with high efficiency gas chromatography columns, and the detector properties which are of importance for qualitative and quantitative analysis are discussed.
