What is Gas Chromatography Column and Its Advantages?

Inside the gas chromatography systems, a GC column is found. Gas chromatography columns are tubes through which solutes are measured at a primary rate. GC Column Supplier supply either packed or capillary style.

Packed GC column Packed GC columns are made of glass and stainless steel coil construction. The total length of the column is one to five-meter with a diameter of five millimeters. The devices are mainly filled with a stationary phase.

Capillary GC columns Capillary GC columns are composed of two major parts and are also known as open tubular columns. Onto the inner wall of small diameter tubing, a thin film of high molecular weight and the thermally stable polymer are coated.

Material Material of GC columns is one of the most important specifications. They are made of stainless stain, glass, or silicate glass. Column length, inner diameter, and film thickness are very important.

Gas Chromatography Column To separate and analyze volatile chemical compounds Gas Chromatography Column technique is used. Within a mixture of test sample purity, it is used to separate different compounds and the equipment used in the GC experiment is called a gas chromatographer. The purpose of inner gas is to carry any unadsorbed molecules through the column and gas is used as a carrier gas. Within a glass or metal column, the stationary phase is specifically a viscous liquid held on an inert solid support.

Advantages of Gas Chromatography

There are some clear advantages of using gas chromatography which are:

• Improved Resolution With GC techniques closely related peaks in the data can be resolved more easily. Parameters can be adjusted in real-time and are suitable for incredibly complex mixtures such as smoke.

• Improved analysis speed The analysis of a sample can be completed in the space as operational parameters can be easily changed. With GC optimum resolution can be achieved quickly.

• Wider sample choice The high boiling points are to be analyzed with the ability to control the temperature of the process. With GC a wider choice of volatile samples can be analyzed.

• Fully quantitative To provide more accurate data than other techniques the software used in gas chromatography.

At lower limits than other techniques, specialized detectors can detect target compounds.

• Column choice Columns available in gas chromatographer are used in a wide range of sizes and used for a wide range of applications. With the help of different stationery and liquid support, a GC experiment can also be carried out.

Conclusion Over more traditional techniques Gas Chromatography Column provides several advantages.

But its disadvantage is that it is limited to thermally stable and volatile compounds which makes it unsuitable for organic samples. If you are searching for Gas Chromatography Column then Quadrexcorp provides the best options.
