PurityPlus® Grade 6.0 Gases by Mississippi Welders Supply Co., Inc.: Greater Production, More Economical Costs

Critical gas users are adamant about having high-quality Carrier Gases for chromatography and the entire range of analytical applications. Providing these gases had better be a core competency of any specialty gas producer. For better than forty years now, both the limited detection abilities of general technology and ever improving analytical processes have justifiably put greater demand on these gases. The gas specifications widely sanctioned in the 1970s could be inadequate for 21st century needs. Meeting or transcending upgraded specs demands a constantly renewed investment by the gas supplier – in instrumentation and purification equipment, in schooling to obtain optimal performance from these agents, and in constant review, testing, and corroboration of manufacturing and quality processes. To keep in front of your needs, we’re upgrading our ability to manufacture and certify the gases essential to your ever expanding applications.

What, then, are you buying? What are you measuring? And what advantages do you gain by acquiring the highest-purity gas your finances allow? Let’s do a quick study of 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 ppm

What’s it all mean? If you’re measuring processes with components in percentage ranges, 5.0 gases are probably acceptable. If you’re measuring impurities in the 10–1,000 ppm range, you’ll achieve a flatter baseline and more precise measurements using 5.5 gases. And if you’re engaged in contaminant detection and quantification below 10 ppm, you’d be better off using 6.0. But standards aren’t all that have to be accounted for. 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 verify these specifications frequently calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
