Liquid Chromatography (LC) vs. Gas Chromatography(GC): Advantages & Disadvantages


In a previous post entitled “What is Liquid Chromatography? What is HPLC (High Performance Liquid Chromatography)” the LC and the HPLC analytical techniques were compared and the main advantages and disadvantages of each one were explained.

The main advantages of liquid chromatography (LC) compared to gas chromatography (GC) are going to be presented in this post.


Advantages of LC compared to GC

  • LC is applied to the separation of any compound that is soluble in a liquid phase such as drugs and pharmaceuticals, nucleic acids, amino acids, lipids, carbohydrates, antioxidants, natural and synthetic polymers and inorganic compounds. GC is applied only to volatile compounds.
  • LC analysis is usually performed at room temperature and therefore compounds that are thermally labile can be analyzed
  • Retention of solutes in LC depend on their interaction with both the mobile and the stationary phase and therefore this technique is more flexible in optimizing separations
  • The LC detectors that are used are usually not destructive and therefore the analytes may be collected for further analysis.  


Disadvantages of LC compared to GC

The main disadvantages of liquid chromatography (LC) compared to gas chromatography (GC) are as follows:

  • LC has always been a slower technique than GC. Analysis times of GC of a few minutes are common. In contrast, LC traditionally has been a slower technique.
  • LC is subject to greater peak or band-broadening and therefore to lower resolution compared to GC.
