MultiGas 2032 Purity FTIR Gas Analyzer from MKS Instruments

The MultiGas Purity Analyzer is an FTIR Spectroscopy based gas analyzer capable of ppb contaminant detection in high purity bulk process gases such as NH3 (Ammonia), NF3, SiF4, and H2. The MultiGas Purity Analyzer is composed of a process FTIR Spectrometer, high-optical-throughput internally polished sampling cell, and applications-specific gas analysis software. These integrated components, along with automated bake-out functionality, provide unmatched precision and accuracy for bulk gas contaminant monitoring.
