Automation of a Residual Gas Analyzer on a Time-shared Computer

, Abstract: The automation of a quadrupole mass spectrometer residual gas analyzer (RGA) on a time-shared IBM 1800 Data Acquisition and Control Computer is described. The RGA, which is used to determine the partial pressures of various gases in a vacuum system, may be operated up to a maximum data rate of about 20,000 pointslsec (pps) in an interleaved manner with multiple slow-scanning (520 pp...

Vacuum Diagnosis with an RGA

Stanford Research Systems phone: (408)744-9040 www.thinkSRS.com Residual Gas Analyzer (RGA) is the term used for a class of quadrupole mass spectrometers that typically cover mass ranges from 1 to 100 or 200 amu (atomic mass units), and are intended to be used for the analysis of the gasses present in high and ultra-high vacuum. The RGA’s resolution is sufficient to clearly distinguish peaks th...

Comparative Study of the Catalytic Activities of Three Distinct Carbonaceous Materials through Photocatalytic Oxidation, CO Conversion, Dye Degradation, and Electrochemical Measurements

In order to compare the catalytic activities of reduced graphene oxide (rGO), graphene oxide (GO), and graphene, we conducted oxidation of 2-aminothiophenol (2-ATP) and reduction of nitrobenzene (NB) in their presence by using high-resolution photoemission spectroscopy (HRPES). In addition, we determined conversion rates of CO to CO2 in the presence of these catalysts by performing a residual g...

Title: Analysis of Laser Ablation Plumes by Laser-Induced Breakdown Spectroscopy and Quadrupole Mass Spectrometry: a Preliminary Study

Plasma plumes resulting from Nd:YAG laser ablation of copper and Fecralloy (Fe 72.8%, Cr 22%, Al 5%, Zr trace, Y trace) have been analysed simultaneously with Laser-Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Mass Spectrometry (LAMS). A commercially available Residual Gas Analyser (RGA) was employed to perform mass spectrometric analysis of the neutral and ionic species created dur...
