what about mass chromatography?

Question

i want to know about mass chromatography and not spectroscopy(it is a new search).can help

Answer 1

There is no such thing as "mass chromatography"

There is 2 other options that you can be refering to LC/GC/MS systems that separate the elution and atomize the solvent as it comes off the column, and send it to the quadrapole in the MS for detection of mass.

There is also GPC (Gel Permeation) Chromatography which is perhaps more what you might be looking for. This type of system is similar to HPLC, but is lower pressure (100 bar) and instead of separation by Polarity, this particular column will separate by molecular mass; with the larger molecules having the shortest elution time, and the smaller molecules having the longer elution time. This works best if used with a Refractive index detector.
