PurityPlus® Grade 6.0 Gases by Delille Oxygen Company: Expanded Production, More Economical Costs

Critical gas customers insist on high-quality Carrier Gases for chromatography and any application involving analytics. Delivering these gases should be a primary capability of any specialty gas vendor. In the last forty years, give or take, both the limited detection abilities of common technology and evolving analytical processes have demonstrably made these gases more popular than ever. The gas specifications deemed suitable for the 1970s might well be unsatisfactory for 21st century needs. Meeting or beating upgraded specs necessitates a constant investment by the gas supplier – in instrumentation and purification equipment, in instruction to realize optimal performance from these means, and in constant review, testing, and affirmation of manufacturing and quality procedures. To stay a step ahead of your needs, we’re always improving our ability to manufacture and certify the gases you require in the 21st century.

So what are you buying? And what is it you’re measuring? And what’s the advantage of seeking out the highest-purity gas your finances allow? 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 ppm

What can we glean from these specs? If you’re process measuring with components in percentage ranges, 5.0 gases are most likely adequate. If you’re measuring impurities in the 10–1,000 ppm range, you’ll produce a flatter baseline and more exacting 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. But there’s more to account for than simply recognizing standards. There’s our process as well. Are your cylinders pre-treated to eliminate subsequent contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to corroborate these specifications continually calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
