what is the difference between gc pro box and gc pro key

Stronger the interaction between component and stationary phase, slower the elution through the column. Hence, it causes different flow rates for each component through the column, and thus, it leads to the separation of these components. However, these interactions are different from each other for different components in the sample. The components in the sample should interact with the stationary phase.įigure 01: Components of an HPLC Apparatus

The column contains the stationary phase (not moving) which is a solid adsorbent. This technique includes pumping the sample with solvent (the sample to be separated) into a column at high pressure. HPLC is high performance liquid chromatography. Side by Side Comparison – HPLC vs GC in Tabular Form However, both have the same underlying principle of heavy molecules flowing slower than lighter ones. Thus, HPLC applies to constituents that are fluids, but GC is useful when the compounds are gaseous or the compounds that undergo vaporization during the separation process. While HPLC refers to High Pressure Liquid Chromatography, GC is simply Gas Chromatography. HPLC and GC are both methods of separation of compounds from a mixture.

The key difference between HPLC and GC is that HPLC uses a solid stationary phase and liquid mobile phase whereas GC uses a liquid stationary phase and gaseous mobile phase.
