The Michell Instruments QMA401 Trace Moisture Analyzer is designed to provide reliable, fast and accurate measurement of trace moisture content in a variety of applications where keeping moisture to a minimum is of critical importance.

The analyzer utilizes a new generation of precision crystal oscillators, guaranteeing high accuracy moisture measurements which are completely insensitive to changes in background gas composition. While measurements at quantities of moisture less than 1 ppmV stretch the capabilities of other technologies, the new QMA401 offers reliability, simplicity and greatly reduced cost of ownership from the industry-proven Quartz Crystal technology.

The analyzer utilizes a mass flow controller to ensure precise control of the sample and reference gas flows to ±0.1ml/ min. Coupled with a pressure transducer, this system ensures continued accuracy of measured and calculated parameters even during fluctuations in sample pressure.

Applications for the QMA401 include:

  • High purity gas production
  • Air separation plants
  • Semiconductor CVD chamber cleaning
  • Semiconductor etching chambers
  • H2 coolant for generators
  • Polymer chip drying
