Process & Environmental The two-in-one high-sensitivity analyzer • NDIR absorption method with unique cross- flow modulation technique. • Designed to measure impurities in bulk gas (N2) used in semiconductor and other high-purity gases such as He, O2, Air and Ar, used in clean rooms, medical facilities and manufacturing processes. • Simultaneous and continuous measurement • Compact and lightweight, fits in a standard HORIBA is a worldwide leader in non-dispersive infrared (NDIR) technology and a major NDIR analyzer manufac- turer. The heart of the GA-360E Trace Gas Monitor is the multinational^ accepted, field-proven, cross-flow modu- lated HORIBA NDIR analyzer. Highly reliable trace gas monitors The GA-360E represents a concept in trace gas monitors, is designed to eliminate routine calibration cycles and to provide long-term stable measurement and continuous unattended operation. It furnishes reliable concentration. Every element of the monitor has been selected to offer the ultimate in reliability and accuracy. Solid-state modular electronics ensure optimum performance and minimum Available in one-or two-component versions The GA-360E is available in a one-component version to measure a single component, or a two-component versions specified by the customer. Simultaneous measurement of two different components is made possible by linking two detectors to the main unit via a single sample line.

light source reference gast BPA-PSD: Brand Pass Amplifier Phase Sensitive Detection An infrared beam in the analyzer unit passes through the cell to the detector. During measurement, the solenoid valves alternately tensity of the light reaching the detector when the cell is filled with sample gas from when it is filled with reference gas. This defference causes a metalic membrane in the detector to move back and forth in accordance with the alternating gas flow (cross-flow modulation). The analyzer requires neither an optical chopper nor optical adjustment. Furthermore, this technique virtually...
