Single Pumping System and Differential Pumping System
When we compare a differential pumping system to a single pumping system, a vacuum in the vicinity of the MS analyzer and detector is about 5 to 10 times better for a differential system than the single system. In cases where we use the performance of a TMP for a single pumping system and the ion source side of differential pumping system, we can afford to flow more amount of carrier gas into the MS.
