Effects of Collector Probe Irregularities in Electron Capture Gas Chromatography
Keyword(s):
Abstract Barely visible scoring of a cylindrical electron collector probe had profound effects on the performance of an electron capture detector in gas chromatography: Electronic noise was increased greatly, relationship of response to applied voltage was reversed, and optimum distance between the probe and the radioactive source was shifted widely. Imperfections too small for visual detection, although having little effect on noise and response levels, were found to cause serious baseline instability. An instrumental error of as much as ± 50% due to surface irregularities can be eliminated by polishing the collector probe.
