Answer:D
Which of the following detectors is widely used to detect environmental samples like chlorinated pesticides and polychlorinated biphenyls?
A. Flame ionization detector B. Thermal conductivity detector C. Argon ionisation detector D. Electron capture detector
Explanation: Electron capture detector is used to detect environmental samples like polychlorinated biphenyls and chlorinated pesticides. It is highly sensitive to molecules containing functional groups such as halogen and phosphorous.
