PurityPlus® Grade 6.0 Gases by Cee Kay Supply, Inc.: Increased Production, Lower Costs Critical gas users are adamant about having high-quality Carrier Gases for chromatography and any application involving analytics. Offering these gases had better be a primary capability of any specialty gas producer. For something like forty years or so, the detection limitations of most existing technology as well as constantly advancing analytical methods have naturally increased the demand for these gases. The gas specifications deemed suitable for the 1970s may be unsatisfactory for 21st century needs. Meeting or surpassing modernized specs necessitates a steady investment by the gas supplier – in instrumentation and purification equipment, in tutelage to realize the very best performance from these tools, and in constant review, testing, and affirmation of manufacturing and quality programs. To continue anticipating your needs, we’re always improving our ability to manufacture and certify the gases essential to your ever expanding applications. Have you recently reviewed your gas buys and what you’re measuring? Have you seriously considered just how advantageous it is to go after the highest-purity gas your finances allow? 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 it all mean? If you’re doing process measurement with components in percentage ranges, 5.0 gases are generally okay. 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 doing contaminant detection and quantification below 10 ppm, you’d be better served using 6.0. But standards aren’t all that require paying attention to. Our process is just as critical. Are your cylinders pre-treated to escape eventual contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to affirm these specifications regularly calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
