Residual Gas Analysis (RGA) is a routine diagnostic tool for any vacuum engineer but the traditional upper working limit of 1e-4 mbar total pressure is restrictive for many process applications. The HPQ3 RGA allows operation up to 0.001 Torr without the need for differential pumping. The field proven technology of the HPQ analyser coupled with the latest innovative electronics platform derived from the Microvision 2 family give data quality not previously seen in this class of instrument. The resulting system is less complex, with reduced installation requirements, offering a higher level of reliability at a substantially lower cost.
HPQ3 High Pressure Residual Gas Analyzer are available with the following options.

MKS was the first company to offer an RGA compatible with modern Ethernet based, web-enabled, wide area network installations. HPQ3 continues this development to a level that offers the highest flexibility and connectivity through the use of industry standard communication hardware and software. HPQ3 optimizes the roles required of a complex sensor by having two dedicated processors;
The advantages of this design approach are fast, accurate data from a robust RGA sensor using industry standard, flexible communication protocols. HPQ3 also provides a complete range of additional digital and analog connections for integrating into systems with flexible low cost solutions.
The new RF design in the HPQ3 covers the 1-100 amu mass range without compromising the quality of gas peak separation at very low mass or high mass. The field proven High Pressure Quadrupole analyser design in the HPQ3 retains the robust and inexpensive ion source design with dual filaments. This allows continuous uninterrupted operation without needing to regularly replace filaments before their normal expected lifetime. The HPQ3 can be used for processes where data is required up to a total pressure of 1.3 x 10-3 mbar.
The patented wide dynamic range detector electronics allow detection of single figure parts per million chamber leaks or contaminants, even when simultaneously measuring major gas peaks in the e-3 mbar range. This is possible in a single scan or peak jump data acquisition with less than 20 ms between the maximum and minimum signal levels and without the need for an expensive electron multiplier which needs frequent calibration and replacement.
A web interface using industry standard technology allows set-up and control of the HPQ3 from anywhere on a network. Using a non platform-specific web browser, calibration, operation and saving real time data to an export format is all possible. Using the documented Software Developer’s Kit, ASCII protocol and TCP-IP communication, any third party software can send and receive commands and data from the HPQ3 and HPQ3S.
