PurityPlus® Grade 6.0 Gases by American Welding & Gas, Inc.: More Production, Lower Costs Those who use critical gases must have high-quality Carrier Gases for chromatography and anything analytical. Offering these gases ought to be foremost among the skill sets of any specialty gas producer. For something like forty years or so, both the narrow detection capabilities of typical technology and ever evolving analytical techniques have rightly put more demand on these gases. The gas specifications that addressed 1970s needs adequately might well be inadequate as this century unfolds. Meeting or surpassing upgraded specs necessitates an unbroken investment by the gas supplier – in instrumentation and purification equipment, in tutelage to realize maximum performance from these methods, and in continuous review, testing, and affirmation of manufacturing and quality programs. To continue anticipating your needs, we’re upgrading our ability to manufacture and certify the gases you require in the 21st century. Have you paid real attention lately to your gas buys and what you’re measuring? Have you seriously considered just how necessary it is to purchase the highest-purity gas you can afford? Let’s cast an eye on 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 the upshot here? If you’re doing process measurement with components in percentage ranges, 5.0 gases are probably good enough. If you’re measuring impurities in the 10–1,000 ppm range, you’ll produce a flatter baseline and more accurate measurements using 5.5 gases. And if you’re performing contaminant detection and quantification below 10 ppm, you’ll come out ahead using 6.0. In any event, recognizing standards isn’t all there is to it. There’s also our process]86]. Are your cylinders pre-treated to avoid eventual contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to confirm these specifications regularly calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
