![]() Never permit smoking or open flames in oxidizer or flammable gas storage areas. ![]() Never allow storage temperature to exceed 125☏ (52☌).Cylinders must be stored in an upright position.The only time the cap should be removed is while it’s being used. Valve protection caps must be in place during transit or storage.Secure cylinders by firmly chaining or strapping them to a wall, lab bench, or other fixed support. Cylinders must be secured with an appropriate strap or chain when in storage, transit, or use.Only BIP ® gases are guaranteed to meet specifications even when the cylinder pressure is less than 500 psig (34 barg). In contrast, gas supplied in conventional cylinders often does not meet the listed specifications at lower pressures, since the specifications apply only for a fully pressurized cylinder. The BIP ® purifier system guarantees that all gas exiting the cylinder, no matter how full or empty it is, meets these exacting specifications. Note that these specifications are for the product gas, not the gas residing in the cylinder. Experis ® gases with BIP ® technology feature impurities as low as <10ppb total hydrocarbons, <10ppb oxygen and <20ppb moisture. Unmatched PurityīIP ® cylinders deliver the highest purity helium, nitrogen, hydrogen and argon available. Plus, the unique cylinder valve prevents accidental back streaming of air during cylinder exchange or during cylinder refilling. We can make this claim because we designed the capacity of the purifier bed in excess of that needed to meet our guaranteed specifications and this is proved by rigorous quality control. It allows us to guarantee unmatched purity specifications for each and every BIP ® cylinder, no matter when or where you order them. That's why we developed the BIP ® technology. You never know when you'll get a rogue cylinder, and neither does the gas supplier. And, ironically, purifiers allow the rogue cylinder to escape undetected contaminants from a rogue cylinder captured by the purifier train may break through and contaminate the system long after the actual culprit cylinder has been replaced.Purifier disposal must be done carefully in an environmentally friendly way - costs of this are rising. Purifiers entail capital and labour investments for proper maintenance.Checking purifier performance requires time and instrumentation you may not have.Purifiers can become saturated or consumed, allowing contaminants to break through.The purifiers don't remove all impurities equally well.At least two fittings downstream of the last purifier train element are not controlled.Many chromatographers install in-line purifiers to remove impurities that vary from cylinder-to-cylinder and to protect their instruments against the "bad gas" from the rare but real, highly contaminated cylinder that we call a "rogue" cylinder.Īlthough in-line purifiers can effectively ensure gas quality at the point of purification, they are not a perfect solution: This means that most cylinders are not individually analyzed neither the gas supplier nor the end user really know the impurity levels. The fact is, gas suppliers rely upon statistical quality control and batch testing to certify gas purity. GasĪs a gas chromatographer, you may question whether the gas in the cylinders connected to your instruments consistently meets specified purity levels. The BIP ® purification technology enables you to use argon, nitrogen, hydrogen and helium that are up to 300 times purer than normal cylinder gases.Įxperis ® gases with BIP ® technology are available in 3 grades, featuring impurities as low as <10ppb total hydrocarbons, ≤ 10ppb oxygen and ≤ 20ppb moisture.
