High performance liquid chromatography (HPLC) is an analytical technique used to separate, identify, quantify, and purify individual components of a mixture. This technique is very common in ...

In this lab, students will determine the amount of caffeine in a beverage. Students will determine the retention time of pure caffeine. From this information, students will be able to identify the ...

For some chromatographers, their first inkling that high-performance liquid chromatography was going to be a big deal came in 1969. That year, they traveled to Las Vegas to attend the fifth in a ...

There are a few scenarios where analytical procedures might need to be transferred between HPLC instruments: 1) Method transfer to new equipment in the same lab, perhaps to a different vendor or a ...

High-performance liquid chromatography or high-pressure liquid chromatography (HPLC) is a chromatographic method that is used to separate a mixture of compounds in analytical chemistry and ...

High-performance liquid chromatography (HPLC) is an analytical chemistry technique used to separate liquid mixtures of compounds or analytes. The method employs a liquid "mobile phase" to transport ...

This article presents a simple and systematic approach to HPLC method development, beginning with sample preparation and finishing with practical analytical method validation. step 5 - method ...

When conducting reproducible and interference-free analysis by liquid chromatography, the purity of the solvents used, particularly the purity of water, is crucial for the sensitivity of this method, ...
