Source of hydrogen should be delivered through brand new stainless steel or systematic grade copper tubing. It is significant to convert the tubing that was formerly used to source helium to the gas chromatography, over prolonged time, residues can build up on the interior of the tube which hydrogen will shred out, generating higher background signal for a lengthier period of time.
Hydrogen, can be functional over a wide range of rectilinear velocities while upholding a low height corresponding to a theoretical plate or HETP. This empowers the utilisation of a linear velocity greater than ideal with minimum fall in competence, ensuing in lesser analysis times.
