WebAug 15, 2024 · Retention Factor. Since K c is a factor that is wholly dependent on a particular column and solvent flow rate, a quantitative measure of the affinity of a compound for a particular set of mobile and stationary phases that does not depend on the column geometry is useful. The retention factor, k, can be derived from K c and is independent of … WebCalculate the saving in run time and solvent consumption when transferring a method from HPLC conditions to UHPLC conditions.

Retention and peak width are used to calculate various performance measurements; in this way, the separating power of a system can be calculated and compared. However, in order to do this, the chromatographer must rely on two fundamental theories of chromatography: (i) the plate theory; and (ii) the rate theory.
WebJun 21, 2024 · Therefore, it was strongly necessary to set the make-up gas of the capillary column. Traditionally, the sum flow rate of carrier gas and make-up gas of the capillary column in FID detector is about 30 mL min − 1 [34,35,36]. Small make-up gas flow could improve the sensitivity, but it was prone to peak tail, affecting the peak shape, and vice ...
