Identify the detector or detectors that can be used in gas chromatography for the detection of each type of analyte. More than one detector may be appropriate for a given analyte, and a given detector may be appropriate for more than one type of analyte.

1. Carbon atoms bearing hydrogen atoms

2. Molecules with halogens, CN, NO2, conjugated C=O

3. Aromatic and unsaturated compounds

4. P and S and other elements selected by wavelength.

5. P and N (and also hydrocarbons)

6. S

choices are

flame ionization, electron capture, flame photometric, nitrogen-phosphorus, photoionazation, sulfur chemiluminescence, mass spectrometer, thermial conductivity
