In an analytical or process environment, reliable results and trouble-free operation start with ultra high purity gases. Air Products understands the impact that impurities can have, so we designed a range of Ultra High Purity (UHP) gases, containing the lowest level of critical impurities on the market, specifically for the analytical user.
Our UHP helium can help you meet your most stringent requirements
- Lowest levels of critical impurities on the market
- Certified maximum impurity levels
- Large range of packages to suit your requirements: from small 0.4 liter cylinders to packs of 18 large cylinders
- Comprehensive range of UHP gas control equipment, including regulators and manifolds, designed to highest standards and extensively leak tested
Get the ultimate carrier gas with Air Product's exclusive BIP® technology
Whenever ultra pure helium carrier gas is required for analytical processes such as gas chromatography, protein analysis and much more, our unique patented BIP® cylinder gives the confidence that comes from knowing you have the highest purity carrier and makeup gases available-without the inconvenience, uncertainty and hassle associated with external purifiers.
BIP® helium
- 300 times purer than in any conventional cylinder
- < 10 ppb O2
- < 20 ppb H2O
- 0 process contamination
- 100% consistency
- Improved performance and life expectancy of your instrument
- Specific grade for ECD applications with Halocarbons < 1 ppb
Our specialists can help you select the optimum gas for your application.
