PurityPlus® Grade 6.0 Gases by Rocky Mountain Air Solutions: Increased Production, Improved Economics Critical gas users 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. Over the past forty years, the narrow detection capabilities of general technology in addition to evolving analytical techniques have justifiably expanded the utility of these gases significantly. The gas specifications deemed suitable for the 1970s may be unsatisfactory for 21st century needs. 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 auditing 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. Have you recently reviewed your gas purchases and what you’re measuring? Have you honestly appraised just how truly beneficial it is to seek out the highest-purity gas you can afford? 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 involved 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.
