PurityPlus® Grade 6.0 Gases by Arc3 Gases: Increased Production, Greater Cost Economies

Those who use critical gases are adamant about having high-quality Carrier Gases for chromatography and the entire range of analytical applications. Supplying these gases ought to be a primary capability of any specialty gas producer. For something like forty years or so, both the narrow detection capabilities of common technology and ever better analytical processes have demonstrably made these gases more popular than ever. The gas specifications that took care of 1970s needs well enough may prove inadequate as this century progresses. Meeting or transcending ever new specs necessitates a continual investment by the gas supplier – in instrumentation and purification equipment, in tutelage to get optimal performance from these tools, and in frequent review, testing, and verification of manufacturing and quality processes. In order to stay a step ahead of your needs, we’re upgrading our ability to create and certify the gases essential to your ever expanding applications.

So what are you purchasing? And what are you measuring? And what’s to be gained by acquiring the highest-purity gas you can afford? Let’s look closely at the PurityPlus Specifications.

What’s it all mean? If you’re doing process measurement 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 realize a flatter baseline and more precise 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. 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 eventual 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.
