Chemistry · L4 · Instrumental Chromatography — HPLC and GC

How HPLC and GC separate and identify compounds without a visible spot: pumped liquid through a packed column vs vaporized sample swept by carrier gas through a heated column, and retention time as the instrumental analog of Rf — flashcards, a reference note with an HPLC pipeline diagram and a comparison table, a standalone GC pipeline diagram, and a quiz.
