The illustration below shows how the mobile phase pH in liquid chromatography affects our ability to separate a mixture of four substituted benzoic acids. The retention times in (a) suggest there are many […]
Adjusting the retention factor to improve the resolution between one pair of solutes may lead to unacceptably long retention times for other solutes. For example, suppose we need to analyze a four-component […]
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 […]
