PurityPlus® Grade 6.0 Gases by Sidney Lee Medical & Scientific Gases: Greater Production, Greater Cost Economies

Critical gas customers won’t settle for less than high-quality Carrier Gases for chromatography and any job requiring the application of analytics. Providing these gases should be a core competency of any specialty gas vendor. In the last forty years, give or take, the narrow detection capabilities of general technology coupled with ever better analytical processes have justifiably put more demand on these gases. The gas specifications deemed suitable for the 1970s may be inadequate for 21st century needs. Meeting and exceeding ever new specs necessitates an ongoing investment by the gas supplier – in instrumentation and purification equipment, in education to coax peak performance from these means, and in frequent review, testing, and auditing of manufacturing and quality checks. So that we can stay a step ahead of your needs, we are expanding our ability to manufacture and certify the gases essential to your ever expanding applications.

Have you paid real attention lately to your gas acquisitions and what you’re measuring? Have you seriously considered just how necessary it is to seek out the highest-purity gas you can afford? Let’s cast an eye on 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 doing process measurement with components in percentage ranges, 5.0 gases are probably okay. If you’re measuring impurities in the 10–1,000 ppm range, you’ll achieve a flatter baseline and more exacting 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 just about taking standards into account. It’s also about our process. Are your cylinders pre-treated to prevent subsequent contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to confirm these specifications continually calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
