oxygen concentrator[/url] is a medical device that 

concentrates oxygen from ambient air. Atmospheric air 

has about 78 per cent nitrogen and 21 per cent oxygen, 

with other gases making up the remaining 1 per cent. The 

oxygen concentrator takes in this air, filters it 

through a sieve, releases the nitrogen back into the 

air, and works on the remaining oxygen. It's only a 

little bigger than a computer monitor, yet as cases 

surge and with oxygen cylinders in short supply across 

several states, the concentrator is among the most 

sought after devices for oxygen therapy, especially 

among patients in home isolation and for hospitals 

running out of oxygen.

This oxygen, compressed and dispensed through a cannula, 

is 90-95 per cent pure. A pressure valve in 

concentrators helps regulate supply, ranging from 1-10 

litres per minute. According to a 2015 report by the 

WHO, concentrators are designed for continuous operation 

and can produce oxygen 24 hours a day, 7 days a week, 

for up to 5 years or more. And it can be called in many 

different ways like

Except for oxygen, hydrogen can be account for another 

important gas in the world. Hydrogen is the most 

abundant element in the Universe, although in its 

gaseous state it does not naturally occur on Earth and 

must be manufactured. In industry, H2(g) is produced on 

a large scale by a process called steam reforming, to 

separate carbon and hydrogen atoms from hydrocarbon 

fuels. Hydrogen is used in the laboratory for a variety 

of lab applications such as Gas Chromatography (GC) as 

fuel or carrier gas and ICP-MS as a collision gas, in 

the chemical industry to synthesise ammonia, cyclohexane 

and methanol and in the food industry for hydrogenation 

of oils to form fats.

Significant research and development has afforded safer, 

greener, more efficient and cost-effective means of 

generating on-demand hydrogen gas for laboratory, 

manufacturing and industrial applications. Safety has 

improved so much that Hydrogen gas is now being used in 

some transport vehicles as a clean ‘pollution-free’ 

fuel with the gas being generated from water with the 

by-product of its combustion being water.
