PurityPlus® Grade 6.0 Gases by Rocky Mountain Air Solutions: Increased Production, Lower Costs Critical gas customers won’t settle for less than high-quality Carrier Gases for chromatography and any job requiring the application of analytics. Providing these gases should be a core competency of any specialty gas vendor. In the last forty years, give or take, the detection limits of general technology in addition to ever-improving analytical techniques have justifiably expanded the utility of these gases significantly. The gas specifications that addressed 1970s needs properly may prove unsatisfactory as this century moves forward. Meeting or beating upgraded specs necessitates a constantly renewed investment by the gas supplier – in instrumentation and purification equipment, in tutelage to coax maximum performance from these agents, and in constant review, testing, and corroboration of manufacturing and quality methodologies. In order to keep in front of your needs, we are expanding our ability to create and certify the gases you depend on in the 21st century. So what are you purchasing? And what are you measuring? And what’s so important about going after the highest-purity gas your finances allow? Let’s examine 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 ppmWhat’s it all mean? If you’re doing process measurement with components in percentage ranges, 5.0 gases are generally adequate. 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 doing contaminant detection and quantification below 10 ppm, you’d be better served using 6.0. But there’s more to account for than simply recognizing standards. There’s our process as well. Are your cylinders pre-treated to eliminate later contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to confirm these specifications frequently calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can. If you’re a Denver user of high-purity gases, PurityPlus® by Rocky Mountain Air Solutions should be your top choice. We’ve put our money in tools and people. We actively join in an all-inclusive round-robin program to test our capabilities.
