Question

Match the detector or detectors that can be used in gas chromatography for the detection of the following list of analyses by dragging the detector into the box to the left of the analytic. (More than one detector may be appropriate for a given analytic, and a given detector may be appropriate for more than one group of analyses.) Carbon atoms bearing hydrogen atoms Molecules with halogens, CN, NO_2, conjugated C=O Aromatic and unsaturated compounds P and S and other elements selected by wavelength. P and N (and also hydrocarbons) S

Explanation / Answer

Themal conductivity detector is universal detector than can be used for wide variety of components

detection limit is 0.002 to 0.02 micrograms/L

vapour and gaseous samples are the most applicable samples for the Photoionization detector(PID)

hence from the given samples PID is used for S.

AED(atomic emmision detector) and Nitrogen Phosphorous detector for P,N at selected wavelengths, detection limit is picogram.

ECD(electron cpature detector for haloginated hydrocarbons (molecules with halogens), detection limit 5fg/s

aromatic unsaturated compounds, carbon atoms bearing hydrogen atoms can be detected by, Mass spectrometer, thermal conducter, Flame ionization detectors.
