Apparatus and a method for detecting and measuring trace gases in air or other gaseous background |
摘要 |
An improved drift tube wherein the high voltage electric field is generated as a function of atmospheric pressure. Such variation of the electric field provides good compensation for the effects produced by changes in atmospheric pressure. As a result, the identification of a particular compound at different altitudes is greatly simplified.
