Smart Performance

Equipped with an ion source that features high sensitivity and long-term stability, and a high-efficiency collision cell, the New Flow Controller Achieves Exceptional Split filter
™
system can provide sensitive, stable analyses over a long period of time. Also, since it incorporates the Nexis GC-2030, Reproducibility
high-precision control over flowrate and temperature is assured, enabling the acquisition of highly reliable data.
A new flow controller (AFC) with a CPU uses various control methods to control carrier gas
flow to a constant flow speed, flowrate, or pressure. It can also accurately trace the analytical
conditions already being used.
Highly Sensitive and Stable Ion Source The split line filter can be replaced without any tools. Internal contamination can be confirmed
visually, ensuring filters are replaced at the proper time.
The effect of the filament’s electric potential on the ion source is
reduced by placing more distance between the filament and ion
source box. In addition, a shield blocks out radiant heat generated
from the filament to ensure the ion source box temperature
remains uniform. Since this prevents any active spots within the Valve
ion source, it provides higher sensitivity for analysis.
