The C18 column is a variety of reverse-section chromatography column. That column has octadecylsilane as its stationary phase.

It seems odd the a lot more common kind of liquid chromatography is determined as reverse-period in lieu of typical period. You may perhaps remember that among the earliest samples of chromatography was Mikhail Tswett’s separation of plant pigments using a polar column of calcium carbonate and also a nonpolar cell section of petroleum ether. The assignment of usual and reversed, website therefore, is all about priority.

Because the stationary stage is polar, the mobile phase is really a nonpolar or perhaps a moderately polar solvent. The mixture of a polar stationary phase as well as a nonpolar cell section is termed usual- period chromatography

The cellular period’s move rate is determined through the mixed speeds of the two pumps. By modifying the relative speeds of the two pumps, different binary mobile phases can be ready.

The separation selectivity might be afflicted by numerous parameters that include cell period ailments, stationary stage chemistry as well as the instrument set up.
