Smart Performance

Provides Higher Sensitivity and Reduces Operational Costs

A large-capacity differential exhaust turbomolecular pump and a high-performance flow controller ensure that the New Flow Controller Achieves Exceptional Reproducibility Split filter
utmost in sensitivity is obtained under all conditions used for GC. This sensitivity combined with high-speed analysis
capabilities helps maximize laboratory efficiency by reducing analysis times. In addition, the system can be safely A new flow controller (AFC) with a CPU uses various control methods to control carrier
operated using carrier gases other than helium, such as hydrogen or nitrogen, thereby reducing operating costs. gas flow to a constant flow speed, flowrate, or pressure. It can also accurately trace the
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
high-sensitivity analysis with long-term stability. (Patent: US7939810) (AFC-2030)

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.
