Specialized Gas Mixtures: Advancements in gas chromatography and mass spectroscopy have enabled the development of highly specialized gas mixtures for calibration, analysis, and industrial applications. Precision in mixing gases to specific compositions has enabled usage across critical sectors such as pharmac...
Helium replaces nitrogen in diving gas mixtures, so that divers can go deeper under water without negative central nervous system effects. Without this mixture, divers could suffer from pressure effects with the condition called "the bends." There are numerous scientific uses of helium. The Large...
Volume fractions in gas mixtures From Avogadro's Law we know that "equal volumes contain equal numbers of molecules". This means that the volumes of gases, unlike those of solids and liquids, are strictly additive. So if a partitioned container has two volumes of gas A in one section and...
Diving technology To weld lengths of pipeline on the seabed, it is often necessary to dive to extreme depths. Special gas mixtures are used to supply breathing air for this purpose. Here oxygen and helium (Heliox) or oxygen, nitrogen and helium (Trimix) are used. The diving gas Heliox usua...
This position of valves both inside the bell 20 and outside the work chamber 10, for example, at a controller panel, permits outside instructor personnel to take over control of bell pressure and of gas mixtures, should that become necessary. ...
