Airgas zero air generators produce a continuous flow of air from an existing compressed air supply. In conjunction with our hydrogen generators, these units help gas chromatographers automate GC-FID sampling with reliable, unattended gas supply. Our zero air generators reduce the total hydrocarbon content (THC) to less than 0.1 ppm (measured as methane) and produce stable baselines for reproducible GC-FID analysis. An inlet 0.5-micron coalescing filter removes particles, oil, and water from the air supply. Hydrocarbons are removed when the compressed air is passed over a converter containing a heated catalyst. After the air is cooled, a 0.01-micron cellulose filter removes any residual particles from the stream.
