               analytical conditions already being used.
 Technology Achieves High Sensitivity  The split line filter can be replaced without any tools. Internal contamination can be
               confirmed visually, ensuring filters are replaced at the proper time.

 Ion Source Featuring High Sensitivity and Long-Term Stability
 The filament and the ion source box have been separated, which reduces
 the impact of the filament potential on the interior of the ion source.
 In addition, a shield is provided to block radiant heat generated by the
 filament, achieving a uniform temperature inside the ion source box. Thus,                    Valve
 active spots inside the ion source are not prone to occur, enabling                      Flow Controller

 Large-Capacity Differential Exhaust System
 Through adoption of a new type of turbomolecular pump with increased exhaust efficiency, the
 system's performance is greatly improved when using hydrogen or nitrogen, in addition to   ClickTek Nut
 helium, as the carrier gas. Moreover, a differential exhaust method is used to create a vacuum
 separately for the ion source and the quadrupole. As a result, an optimal MS state can be
 realized regardless of the conditions imposed by the carrier gas used.
