PurityPlus® Grade 6.0 Gases by Criogas: Increased Production, Improved Economics

Those who use critical gases demand high-quality Carrier Gases for chromatography and all analytical applications. Manufacturing these gases should be a primary capability of any specialty gas provider. For something like forty years or so, both the detection limits of typical technology and ever improving analytical techniques have quite expectedly expanded the utility of these gases significantly. The gas specifications widely sanctioned in the 1970s might well be unsatisfactory for 21st century needs. Meeting or transcending modernized specs requires an ongoing investment by the gas supplier – in instrumentation and purification equipment, in education to coax optimal performance from these means, and in frequent review, testing, and affirmation of manufacturing and quality methodologies. So that we can maintain our lead in addressing your needs, we’re upgrading our ability to create and certify the gases you require in the 21st century.

So what are you purchasing? And what is it you’re measuring? And what’s so important about seeking out the highest-purity gas your budget allows? Let’s examine 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 the upshot here? If you’re measuring processes 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 achieve a flatter baseline and more accurate measurements using 5.5 gases. And if you’re doing contaminant detection and quantification below 10 ppm, you probably should be using 6.0. That said, it isn’t merely about adhering to standards. It’s also about our process. Are your cylinders pre-treated to prevent later contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to corroborate these specifications frequently calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
