    CAUTION The various configurations of the 5920 Moisture Analyzer should not produce, or fall victim to, electromagnetic disturbances as specified in the European Union’s EMC Directive. Strict compli- ance to the EMC Directive requires that certain installation techniques and wiring practices are used to prevent or minimize erratic behavior of the Analyzer or its electronic neighbors.

  • Page 10: Gas Compatibility Warning

    SPECIAL WARNINGS AND INFORMATION Gas Compatibility Warning The 5920 analyzer is equipped with two separate gas purifiers which are used to provide sources of dry reference gas in the analyzer. These purifiers are designed for use on spe- cific sample gases. You must make sure that the purifiers installed in your analyzer are WARNING compatible with the sample gas that you are running.

  • Page 15: Overview

    5920 MOISTURE ANALYZER Overview The Model 5920 Moisture Analyzer reliably measures trace concentrations of moisture in ultra-high purity gases such as oxygen, hydrogen, helium, argon, air, neon, xenon and nitrogen at concentrations down to 1 parts-per-billion by volume (PPBV), using a quartz crystal microbalance sensor.

  • Page 16: Controller / Communications

    One RS-232 or one RS-485 serial interface provide communication be- tween the analyzer and your recording or data acquisition equipment. The 5920 analyzer is configured, and analyzer parameters are set, by using either the analyzer display, keypad and function keys, or using an external PC.

  • Page 17: Moisture Sensor

    Moisture Sensor Quartz Crystal Microbalance (QCM) The 5920 analyzer uses a quartz crystal microbalance sensor to measure water vapor concentration. This is a piezoelectric device that is capable of extremely sensitive mass measurement. The QCM is coated with a thin film of hygroscopic material. When gas flows through the sensor, the crystal coating absorbs or desorbs moisture, changing the natural resonance frequency of the crystal.

  • Page 18: Sample Flow

    As such, the Model 5920 is designed to deliver reliable long-term performance from the QCM-based sensor. Sample flow Schematic representations of the Model 5920’s sample manifold are shown in Figure 1-2 through 1-5. These figures represent each of the four operating states used by the ana- lyzer: In normal operation of the analyzer (Figure 1-2 and 1-3), the sample gas enters the ana- lyzer and flows directly through the diaphragm valve (DV1);...

  • Page 19: Solenoid Valves

    As the sensor is alternately switched between the sample and reference gas streams, the Model 5920 microcontroller monitors the frequency changes in the QCM sensor. The dif- ference in frequency measured between the two gas streams is then used to calculate the water vapor concentration of the sample gas entering the analyzer.

  • Page 20: Verification With External Challenges

    Verification with External Challenges Unlike previous AMETEK UHP moisture analyzers, the Model 5920 does not contain an internal moisture standard. In AMETEK’s line of QCM-based moisture analyzers, the primary purpose of the internal moisture standard is to monitor the sensor’s response characteristics and to enable on-line compensation for sensitivity changes that occur over time.
  • Page 21 Figure 1-4 and Figure 1-5 are similar to those of normal operation (Figure 1-2 and Figure 1-3) except that the sample gas passes through the first purifier. After com- pleting the timed zero cycle, the Model 5920 compensates for any minor offsets and the analyzer returns to normal operation.
  • Page 22 10% (i.e., a 2 PPBV change at 20 PPBV) after 45 months of service. Even though the QCM-based moisture analyzers are extremely stable, AMETEK recom- mends that you check the calibration of the analyzer every three years. This performance check should be handled as part of the normal maintenance schedule for the equipment.
