Gas Chromatography Calibration: How to Calibrate GC
Gas chromatography, often abbreviated to GC, is a staple analytical tool in all manner of quality control and research facilities. It is used to detect specific volatile elements in a gas-phase mixture, to quantify the concentration of specific chemicals, and/or to generate a full spectrum of chemical content. This is extremely valuable in a wide range of application bases, from ...

Why Gas Mixers are More Cost-effective than Cylinders in GC Calibration
Gas mixers are not a novel option for gas chromatography calibration, but they are more cost-effective than gas cylinders and becoming a more favorable option. Not only are pure gases cheaper to purchase than pre-mixed gases, but they offer numerous benefits that result in reduced costs and increased profitability. This blog post will look at why gas mixers are a more cost-effective solution ...

5 Benefits of Custom Gas Mixers for Chromatography Calibration
Gas chromatography (GC) is one of the main techniques in separation science. It is used to analyze and quantify the individual constituents of sample mixtures by first vaporizing the sample and injecting it into a column filled with a solid or semi-solid packing media. Different components elute from the column at different rates based on their unique physicochemical properties and their ...

How Mass Flow Controllers Enable Accurate Calibration Standards
Calibration is a critical, yet often overlooked aspect of benchtop chromatography. Guidance on the frequency that gas chromatographic workflows should be calibrated is generally aligned, with the consensus being once every three months is sufficient. However, some believe that calibration can remain stable for up to six months, while other users calibrate as a matter of course before any ...

What Role Does Gas Chromatography Play in Analytical Chemistry?
Analytical chemistry is a complex discipline that focuses on extracting information about the composition and structure of samples using advanced techniques. Generally speaking, these samples must be separated into their component parts for identification and quantification. Thus, separative techniques like gas chromatography (GC) are central to the field. Both qualitative and quantitative ...
