Chromatographic Resolution
The goal of chromatography is to separate a mixture into a series of chromatographic peaks, each representing a single component of the mixture. The resolution between two chromatographic peaks, RAB, is a […]

Retention Time, Baseline Width, and Void Time
A solute’s chromatographic peak may be characterized in many ways, two of which are shown in this figure. Retention time, tr, is the time between when we inject the sample injection and […]
Column Chromatography
The most common method for bringing the stationary phase and the mobile phases into contact is to hold the stationary phase within a column and to pass the mobile phase through the […]
Chromatographic Separations
As illustrated below, in chromatography we pass a sample-free phase, which we call the mobile phase, over a second sample-free stationary phase that remains fixed in space. We inject or place the […]
