Specialty Gas FAQs
Are all 6.0 grade gases the same?
Is gas purity critical for my analytical application?
What are the important impurities to look out for in my UHP gases?
Every analytical technique is different. Often oxygen and moisture can be harmful impurities, which explains the popularity of Air Products BIP technology. For other techniques, hydrocarbons, CO, CO, or other gases can have a negative impact on instrument performance. Most manufacturers of analytical instrumentation will give guidance on the specifications of gases needed for best performance. Some will even highlight the critical impurities to avoid, but many do not. If you do not know, and need advice, our team of experts are on hand to provide it.
What should I be looking for in my UHP gases?
Always look beyond the overall gas purity or grade, and pay special attention to the impurity specifications of all ultra-high purity gases. Once you have selected a gas with the optimum specification, you can then get even more value by thinking about economy, efficiency, and sustainability. As well as delivering ultra-high purity gases with unrivalled specifications of critical impurities like oxygen and moisture, BIP technology provides a number of other important benefits, like more useable gas per cylinder, and the elimination of external in-line purification systems that are costly and inconvenient to maintain.
What are the key factors to look out for when buying a calibration gas mixture?
What is an ISO 17025 mixture?
