The Parker Model 75-82S Zero Air Generator produces up to 1,000 cc/min. of high-purity zero. Using state-of-the-art catalytic technology, the generator continuously converts compressed air into zero-grade air, at safe regulated pressures, and can be used as fuel air to process GC-FIDs, and zero grade gas/zero reference for analytical instruments.

Its housing is a standard Crouse-Hinds® flame-proof enclosure designed to operate in a class 1, division 1, groups B, C, or D environment and its internals are all stainless steel. Zero grade air is produced by means of catalytic
oxidation. Compressed air is channeled into a heated catalyst bed where the hydrocarbons are converted
to carbon dioxide and water vapor, producing zero-grade air with less than 0.1 ppm hydrocarbon
content (measured as methane).
Using a zero air generator for fuel air for GC analysis allows for a lower, more stable baseline signal to be obtained. Lower baseline noise allows for a higher signal-to-noise ratio, giving rise to higher sensitivity or larger peak areas, resulting in increased accuracy and reduced cleaning requirement of the detector.
