High performance liquid chromatography interfacing

HPLC-MS interfaces were developed after GC interfaces and considerably more work was required to produce efficient interfaces capable of dealing with the large vapour volumes from a liquid eluant [8,9]. Possible solutions to the problem include [Pg.379]

Early interfaces used liquid nitrogen or helium cryogenic techniques to remove the solvent vapour, but these were rather cumbersome and not too efficient. Moving belt transport systems were also one of the first interfaces to be developed incorporating a flash vaporiser to remove the solvent before the sample reached the ion source. The main approaches used today are based on thermospray, atmospheric pressure and particle beam interfacing techniques [10]. [Pg.379]

This is not the case when high performance liquid chromatography (HPLC) and MS are considered where, due to the incompatibilities of the two techniques, they cannot be linked directly and an interface must be used, with its prime purpose being the removal of the chromatographic mobile phase. Unfortunately, no single... [Pg.19]
