The calibration gases market is arguably now moving faster than ever. New applications continue emerge every day that require specialty gases in the process. Instrument analysis is required more and more to optimise performance, improve final product quality, and ensure personnel safety in the workplace. New regulations and product specifications continue to appear, each having their unique precision and accuracy requirements. Limits on impurities in pure gases continue to get smaller and smaller, down to parts-per-trillion levels. Accuracy requirements get tighter and tighter with total allowable error in reported certificate values at less than 1 relative to minor component concentration.
