Gas generation system
Whatman Inc. features Zero Air Generators, designed to replace gas cylinders. Four models are available to produce up to 30 ppm of hydrocarbon-free air from an existing compressed air supply. An upgraded design, increased zero air flow rates of up to 20 percent, continuous visual operational status display, and wall-mounting bracketry are new features. The generators will allow gas chromatographers to supply, control and automate their gas supplies for GC-FID`s.
The Zero Air Generators produce lower, more stable baselines than cylinders, significantly enhancing the sensitivity of analysis. The generators reduce the total hydrocarbon content to less than 0.1 ppm, measured as methane.
