As the use of hydrogen offers a notable drop in the time for separation, the analyst could also minimise the column temperature for discrimination. Helium is becoming progressively costly with reports of its price having amplified manifold in some places in between the year 2013 and 2015. Added to its enhanced price, supply can’t be guaranteed in certain places which is galloping the number of labs exploring to switch to hydrogen.
