On the Prima PRO instrument, two resolving slits are fitted – one for low mass peaks (e.g. typically below mass 20 for the Prima PRO and below mass 100 for the Sentinel PRO) and one for high mass peaks. The normal resolving powers used are 20 and 60 for the Prima PRO and 85 and 140 for the Sentinel PRO. -

Introduction Gas samples are introduced into the ion source through the inlet of a Gas probe assembly. For a Prima PRO, gas is sampled through a micro Sample capillary in the stream selector assembly (RMS, solenoid, or single point), passes along a transfer line, into the inlet probe, and finally down a bypass line to the rotary vacuum pump. - Page 143 The dimethylsilicone membrane is fitted to the end of an inlet probe, which replaces the leak element in the Prima PRO assembly. The end of this stainless steel inlet probe locates onto the ion source and is insulated by a ceramic end piece.
