PurityPlus® Grade 6.0 Gases by Wright Brothers: Increased Production, More Economical Costs

Critical gas users are adamant about having high-quality Carrier Gases for chromatography and the entire range of analytical applications. Delivering these gases should be foremost among the skill sets of any specialty gas provider. In the last forty years, give or take, both the narrow detection capabilities of common technology and ever evolving analytical methods have quite expectedly expanded the utility of these gases significantly. The gas specifications that served 1970s needs adequately could be insufficient as this century unfolds. Meeting or surpassing updated specs requires a constant investment by the gas supplier – in instrumentation and purification equipment, in education to get top performance from these agents, and in continuous review, testing, and affirmation of manufacturing and quality processes. In order to continue anticipating your needs, we’re increasing our ability to create and certify the gases you depend on in the 21st century.

So what are you buying? And what is it you’re measuring? And what’s to be gained by 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 ppm

What can we glean from these specs? If you’re process measuring with components in percentage ranges, 5.0 gases are usually 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 performing contaminant detection and quantification below 10 ppm, you’d be better served 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 later contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to verify these specifications cyclically calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
