PurityPlus® Grade 6.0 Gases by AOC Mexico S.A. de C.V.: Larger Production, Greater Cost Economies Critical gas customers insist on high-quality Carrier Gases for chromatography and all analytical applications. Providing these gases ought to be a primary capability of any specialty gas supplier. In the last forty years, give or take, the detection limitations of common technology as well as ever-improving analytical processes have demonstrably put greater demand on these gases. The gas specifications that addressed 1970s needs well enough could prove unsuitable as this century unfolds. Meeting or transcending modernized specs necessitates an ongoing investment by the gas supplier – in instrumentation and purification equipment, in instruction to coax optimal performance from these means, and in continuous review, testing, and corroboration of manufacturing and quality checks. To continue anticipating your needs, we’re upgrading our ability to manufacture 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 acquiring the highest-purity gas your budget allows? Let’s take a look at 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 can we glean from these specs? If you’re process measuring with components in percentage ranges, 5.0 gases are most likely good enough. If you’re measuring impurities in the 10–1,000 ppm range, you’ll achieve a flatter baseline and more accurate measurements using 5.5 gases. And if you’re performing contaminant detection and quantification below 10 ppm, you’d be better off using 6.0. But standards aren’t all that need to be taken into consideration. Our process is just as essential. Are your cylinders pre-treated to escape later 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.
