PurityPlus® Grade 6.0 Gases by WestAir Specialty Gases and Equipment: Larger Production, Improved Economics

Critical gas customers are adamant about having high-quality Carrier Gases for chromatography and every analytical application. Providing these gases had better be a matter of course for any specialty gas vendor. In the last forty years, give or take, both the limited detection abilities of common technology and constantly advancing analytical techniques have quite expectedly expanded the utility of these gases significantly. The gas specifications widely sanctioned in the 1970s may be insufficient for 21st century needs. Meeting or transcending modernized specs demands a steady investment by the gas supplier – in instrumentation and purification equipment, in instruction to coax peak performance from these agents, and in frequent review, testing, and affirmation of manufacturing and quality processes. So that we can maintain our lead in addressing your needs, we’re increasing our ability to create and certify the gases you depend on in the 21st century.

What, then, are you buying? What is it you’re measuring? And what reward is there in going after the highest-purity gas you can afford? Let’s review the PurityPlus Specifications.

PurityPlus Helium,         UHP, 5.0                        Ultra Carrier, 5.5                       Chromatographic, 6.0

Minimum Purity            99.999%                        99.9995%                                  99.9999%

Oxygen                        < 2 ppm                       < 1 ppm                                   < 0.5 ppm

Moisture                       < 2 ppm                       < 1 ppm                                   < 1 ppm

Hydrocarbons              <0.5 ppm                     < 0.5 ppm                                < 0.2 ppm

Nitrogen                                                          < 4 ppm                                   < 1 ppm

Carbon Monoxide                                                                                           < 0.1 ppm

Carbon Dioxide                                                                                               <0.1 ppm

What’s the upshot here? If you’re process measuring with components in percentage ranges, 5.0 gases are probably sufficient. If you’re measuring impurities in the 10–1,000 ppm range, you’ll get a flatter baseline and more precise measurements using 5.5 gases. And if you’re engaged in contaminant detection and quantification below 10 ppm, you’d be better off using 6.0. Nevertheless, it isn’t simply a matter of standards. It’s about our process too. Are your cylinders pre-treated to preclude eventual contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to affirm these specifications periodically calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
