Successfully and safely repeating a test or analysis procedure depends on good process flow and organization. Yet when it comes to supplying high purity gases for critical processes, too many simply place their high purity cylinder near the work area, strap or chain it to the wall, run some tubing found in the top desk drawer and call it good enough. They sometimes justify the decision as a matter of convenience or cost savings, but it is largely a lack of awareness about alternatives.
European companies shifted to using a central gas supply (CGS) for high purity gases decades ago, and they have proven that a CGS offers four key benefits: safety, economics, workflow efficiency and purity assurance. A CGS locates the main source of gas outside of the primary work area (or at least isolates or confines it). The main source of gas may be a single cylinder, cylinder bundle, bulk tank or cryogenic system. A manifold system controls flow at the gas source, where it is then piped to the point of use and controlled by an individual pressure or pressure/flow control regulator.
By recommending the correct CGS system, gas suppliers can position themselves as a cost-savings partner with customers in many industries including:
