The next generation Advanced Quartz Crystal Microbalance analyzer from Michell Instruments 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 provides consistently accurate measurements of trace moisture. This consistency is achieved using a self-calibration system, which adjusts the sensor with reference to an internal moisture generator. The moisture generator is supplied with a calibration traceable to NPL and NIST, so long term stability of its measurements is guaranteed.
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
