Ambient air consists of many gasses, but of that mix, only 19% of it is oxygen. Many applications will require a higher percentage than the 19%. That's where Concentrated Oxygen fills the need.Concentrated Oxygen refers to oxygen which is a minimum of 90% pure with moisture removed to a -100 deg F dew-point.It can be produced from an oxygen concentrator or delivered in a pressurized cylinder bottle.mbient air consists of many gasses, but of that mix, only 19% of it is oxygen.

Globally, it doesnât sound like much â just 0.049 millimetres per year â but if all the sea ice currently bobbing on the oceans were to melt, it could raise sea level by 4 to 6 centimetres. Fresh water, of which icebergs are made, is less dense than salty sea water. So while the amount of sea water displaced by the iceberg is equal to its weight, the melted fresh water will take up a slightly larger volume than the displaced salt water. This results in a small increase in the water level.
Sea IceSea ice includes frozen sea water, such as that in the Arctic Ocean and the oceans surrounding Antarctica, and frozen lake and river water, which occur mainly in the polar regions. Sea ice is formed by the direct freezing of the water on which it floats. If the water is salty, as it is in the ocean and in seas, during the freezing process the salt is left in the water, making the water more salty and denser and the sea ice less salty. Lake and river ice is frozen from fresh water generally and is therefore, not salty.
