The Instrumentation Products Division of Parker Hannifin Corp. has introduced the Parker gas blending system. It allows users to blend or dilute up to five component gases to produce customized gas mixtures.
The system draws from five separate pure gas sources to generate a controlled blend. Automatic or manual dynamic mixing allows the creation of multiple gas concentrations in real time, minimizing inventory of multicomponent custom gas cylinders and reducing tubing installation requirements.
The gas blending system can be used for gas dilution from 1-to-1 to 10,000-to-1, varying the concentration of both pure and preblended gases. From higher percent to parts per billion (PPB) levels, the system can achieve variable concentrations for automatic calibration of gas chromatographs, FTIRs, process gas analyzers, mass spectrometers, and other gas analytical devices.
