Gas Control Box is used when there is more than one Gas Chromatogragh. It helps to control the flow and pressure of different gases for different GC’s. From a Gas Purification System, purified gases can be supplied to a number of Gas Chromatographs through Gas Control Boxes when each instrument requires different delivery pressure & flow. Gas Control Box is generally installed between Gas Purification system and Gas Chromatograph. It consist of pressure gauge, pressure regulator and toggle valves. This also isolates system. 

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. 

Two types of gas selector box are available one with selector valve, pressure gauge & toggle valve, another with only two toggle valve. 

High efficiency Silica gel & Molecular sieves are used for the purpose of removing moisture from the carrier gas. Silica gel is of indicating type changing its colour from blue to pink on uses which have high moisture capacity. The shape of the molecular sieves is spherical, which yields high mechanical strength & low dusting. Both the materials are of regenerable type. 

Activated charcoal is used for the purpose of removing hydrocarbon impurities from the carrier as well as fuel gases, especially for reducing the errors in analysis while using FID. These materials have a very large surface area & pore diameter to adsorb large size hydrocarbon molecules. 

Removal of Oxygen from gases takes place only with the help of catalytic type of materials, which also work only under specific operating conditions. We use pre-treated catalyst which can be regenerated & has comparatively better activity under normal working conditions. Oxytraps are supplied with either indicating or non- indicating type of catalyst. 

Regeneration or replacement of Oxytrap i.e Oxygen Removal will be required after using of 10 – 15 cylinder of UHP grade cylinder or developed on the use & selection / use of capillary / packed column i.e. if polar column, it must to replace oxytrap & if using ECD (Detector). 

Inline Micron Filters are used to remove dust particles from respective gases . Gas Purification panel removes impurity which are in vapours (gases) form. Cylinder being M.S Body has the tendency to illute dust particles, these particles may come in the line and may go to gas chromatograph

Tubing’s are available in Stainless Steel, Copper, Nylon & Teflon in different Size. It is specially made for chromatograph use. Tubing is good in strength, flexible & in capillary form. 

Tubings are available in different sizes such as: 1/16”, 1/8”, ¼, 3/8”, ½” & 1” &. Other sizes on request. 

Generally a Gas Purification System is supplied to cater the need for a number of Gas Chromatographs. In order to make each Gas Chromatograph operationally independent, one has to use a Mini Gas Station with each Gas Chromatograph with ON/OFF valve for each gas. These are normally fitted on the wall or the Instrument table from where the Gas Purification Panel is visible to indicate the gas inlet & the delivery pressure to the instrument. 
 

Layout of the gas lines from the Gas Purification panel to the instrument table are channelised through these casings. Casing are available in PVC Casing Capping type , M.S powder coated, aluminum powder coated & Metallic type , which are used for laying different size of tubing from one place to another place . It gives professional and excellent look to the laboratory & adequate protection to the tubing . 

Manifold system is connected with the Gas cylinder through flexible tail pipe called Pigtail. It is made up of Teflon tubing (inside) and exterior SS wire braided with flexible protection. The end connectors are suitably designed to fit on the Gas cylinder, Regulator as well as Manifold systems. 

Two types of changeover system are available which are low pressure electronic (digital ) automatic change over & high pressure mechanical automatic change over. We can connect two cylinders of same gases where cut off pressure or cylinder change over pressure can be programmed in digital automatic & cylinder automatically change from line 1 to line 2 as per program, where as in mechanical automatic , the cut off pressure is done by differential pressure regulators and the change over of the cylinder is done as per differential pressure set.
