A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm).The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes.A PID may produce instantaneous readings and operate continuously. These hand-held, battery-operated detectors are widely used in military, industrial, and confined working facilities for safety.he first commercial application of photoionization detection was in 1973 as a hand-held detector for the purpose of detecting leaks of volatile organic compounds (VOC's), specifically vinyl chloride monomer (VCM), at a chemical manufacturing facility.
Lab officials also carry out military drug test to detect other drugs other than the mentioned ones. These are random military drug tests, but authorities may carry out specific military drug test for each kind of drug.These drugs include anabolic steroids, ethanol, hallucinogens, inhalants and other banned substances.ctive duty members of the army, navy as well as air force have to undergo military drug test annually. The test is conducted on urine samples and the military laboratory has several inbuilt intelligence and protection system to give accurate results.
