Which statement is true for flame ionization detectors (FID)? a. FID employs a beta emitter to ionize the sample.
b. The detector responds by combusting hydrogen gas from the mobile phase.
c. Emmision spectra are used to quantify the peak concentration
d. The FID flame gets cooler in the presence of hydrocarbon eluent.
e. FID relies on the combustion of the sample carbon atoms which produce CH radicals, CHO+ions, and electrons which are then detected.

The answer would be would be d

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
