WE OFFER THE MOST COMPLETE GAS PRODUCT AND GAS MIXTURES ON THE MARKET
At SII, we offer a wide variety of specialty gas products, ranging from pure gases to the most complex mixed gases. We have the capability to blend multi-component materials packaged into a cylinder. Such gas mixtures will be used by chemical and process specialists, that allow for consistent results and optimum instrument performance. In certain cases that involve application of gas mixtures, a subgroup of gas mixtures is used in analytical systems to make precise comparisons. Each products manufactured and produced at SII meet the tightest specifications with reference to blend tolerance, analytical accuracy, traceability and stability.

Cryogenic liquids are liquefied gases that are kept in their liquid state at very low temperatures and its defined too as a liquid with a normal boiling point below –130°F (–90°C). The most commonly used industrial gases that are transported, handled, and stored in the liquid state at cryogenic temperatures are argon, helium, hydrogen, nitrogen, and oxygen.
