Choosing a Quadrupole Gas Analyzer

Stanford Research Systems phone: (408)744-9040 www.thinkSRS.com Modern-day contamination control requirements for gas phase processes are constantly pushing the limits of performance of quadrupole gas analyzers. The quadrupole technology is rapidly evolving and adapting to lower contamination level specifications. A good understanding of the various factors affecting the detection capabilities ...

Calibration of a Quadrupole Gas Analyzer Using a Reference Gas*

A quadrupole gas analyzer system was calibrated for the gases H2, He, N2, 02, A, and Xe. The procedure involved first calibrating the system for argon, as the reference gas. This was done using conventional techniques. A mixture of the above gases was then introduced into the system to be calibrated. The system configuration was such that the ratio of the partial pressures of each of the test g...

Deuterium Chemistry in the Primordial Gas

We review and update some aspects of deuterium chemistry in the postrecombination Universe with particular emphasis on the formation and destruction of HD. We examine in detail the available theoretical and experimental data for the leading reactions of deuterium chemistry and we highlight the areas where improvements in the determination of rate coefficients are necessary to reduce the remaini...
