Match the detector or detectors that can be used in gas chromatography for the detection of the following list of analytes by dragging the detector into the box to the left of the analyte. (More than one detector may be appropriate for a given analyte, and a given detector may be appropriate for more than one group of analytes.)

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
