Specification :-

« Standard system consists of a panel incorporating gas controls and purification traps for

four gases in a unit, namely, Nitrogen, Helium, Hydrogen and Zero Air.

« Frequent changeover of carrier gas from Helium to Nitrogen is required for certain Gas

Chromatographic applications.

( Hence, Gas selector Box is used for the selection between two gases of different types.

• This uses a special Gas Sampling Valve which takes care of leakage problems especially

faced while using Helium.

t Two types of gas selector box are available one with selector valve, pressure gauge &

toggle valve, another with only two toggle valve.
