High-performance liquid chromatography (HPLC) is a broad analytical chemistry technique used to separate compounds in a chemical mixture. These separations utilize the pressure-driven flow of a mobile phase through a column packed with a stationary phase. Example of an HPLC chromatogram Click image to enlarge
3.2: High Performance Liquid chromatography. High-performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate the components in a mixture, and to identify and quantify each component. It was initially discovered as an analytical technique in the early twentieth century and was first used to separate colored

Apr 24, 2022 · So, there you have it. HPLC is a powerful tool with a wide range of applications. It’s not without its challenges, but its potential is undeniable. Whether you’re a seasoned scientist or a curious newbie, I hope this chat has given you a deeper understanding of HPLC. But remember, this is just the beginning. There’s so much more to learn
Dec 17, 2021 · Pressure. One of the clearest differences between HPLC and UPLC is the pressure they can handle. Previously known as high-pressure liquid chromatography, you might think that HPLC is the superior option. However, while HPLC systems can handle up to 6,000psi, UPLC can handle up to 15,000psi.
Mar 26, 2021 · High-Performance Liquid Chromatography, formerly known as High-Pressure Liquid Chromatography, is a process in which a liquid is passed through a column packed with a specified material to separate components of the liquid. The technique is relatively modern, first being used in the middle of the 20 th century, but it has its roots in work done
