What are the usp limits for the theoretical plates in gas chromatography?

There is no "limit" set by the USP, it depends on the molecules and what is reasonable. For example in HPLC, 2000 plates is typically what you would like to shoot for but if its a compound with low sensitivity and you need to see low levels you might inject more compound which would increase sensitivity but also probably affect peak shape and thus theoretical plates. The answer is it depends
