Multiple Choice
Which statement is NOT true for flame ionization detectors?
A) The detector responds to hydrocarbon analytes,which are burned in a mixture of H2 and air after eluting from the column.
B) During combustion the sample carbon atoms produce CH radicals,which are thought to produce CHO+ ions and electrons in flames.
C) In the absence of analyte,a current of ~10−14 A flows between the flame tip and the collector.Analytes produce a current of ~10−12 A.
D) Flame ionization detectors respond to non-hydrocarbon compounds,but to a lesser degree than hydrocarbons.
E) The detector responds proportionally to analyte mass over seven orders of magnitude.
