Ammonia (氨气） 

Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. The simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products.

Cleaner

Household ammonia is a solution of NH3 in water (i.e., ammonium hydroxide) used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain and stainless steel. It is also frequently used for cleaning ovens and soaking items to loosen baked-on grime. Household ammonia ranges in concentration by weight from 5 to 10% ammonia.

Fermentation

Solutions of ammonia ranging from 16% to 25% are used in the fermentation industry as a source of nitrogen for microorganisms and to adjust pH during fermentation.

Lifting gas

At standard temperature and pressure, ammonia is less dense than atmosphere, and has approximately 60% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas. Because of its relatively high boiling point (compared to helium and hydrogen), ammonia could potentially be refrigerated and liquefied aboard an airship to reduce lift and add ballast (and returned to a gas to add lift and reduce ballast).

Woodworking

Ammonia has been used to darken quarter sawn white oak in Arts & Crafts and Mission-style furniture. Ammonia fumes react with the natural tannins in the wood and cause it to change colours.

Helium （氦气) 

We offer liquid helium and helium gas in a variety of purities and concentrations.
Helium is valued as a gas for lifting, breathing, leak detection, shielding, its inert properties and as a liquid for cooling. Many industries can benefit from its unique properties to optimize performance and productivity, reduce labor costs, and make operations safer.

Hydrogen （氢气）

We offer compressed hydrogen gas and liquid hydrogen in a variety of purities and concentrations.
Hydrogen as a gas is valued for its reactive and protective properties. Many industries such as electronics, foods, glass, chemicals, refining and more can benefit from its unique properties to improve quality, optimize performance and reduce costs.
