Gas chromatography (GC) has long been the backbone of organic chemical analysis.

Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography with the specificity and sensitivity of MS.

Gas chromatography (GC) dates back to the first experiments of Mikhail Tsvet separating plant pigments using paper chromatography in 1903

Selecting the most effective source for high-purity gases is a critical issue for laboratory managers. In-house generation of gases offers the following advantages: gases are continually provided; it is not necessary to replace tanks on a periodic basis; less energy is required to supply gas, since tank gas or liquid nitrogen requires distillation of air and transportation of tanks to the final point of use.

Gas Chromatography in the fast lane - innovations in gas chromatography focus on throughput and flexibility.

Trying to replace a specialty gas with an industrial gas in order to save a few dollars at the onset will cost the buyer more money downstream.

In-house generation promises improved safety, increased convenience and reduced gas costs.
