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.
Thermal expansion: When water heats up, it expands. About half of the past century's rise in sea level is attributable to warmer oceans simply occupying more space. Melting of glaciers and polar ice caps: Large ice formations, like glaciers and the polar ice caps, naturally melt back a bit each summer.
