Liquid chromatography (LC) separates molecules in a liquid mobile phase using a solid stationary phase. Liquid chromatography can be used for analytical or preparative applications. Here, we restrict our discussion to column liquid chromatography techniques and considerations.

2016年2月1日 · overcoming some of the common problems that can occur with columns and fittings in everyday use. The guide covers the main columns used in LC, with particular emphasis on reversed-phase high performance liquid chromatography. How to use this guide: • Sections are color-coded for your easy reference.

Explore our expansive range of prepacked and empty liquid chromatography columns for lab- and process-scale purification workflows. Columns are available in a wide selection of pressure ratings and sizes, and are compatible with common chromatography systems and …

2023年8月29日 · Liquid-solid column chromatography, the most popular chromatography technique and the one discussed here, features a liquid mobile phase which slowly filters down through the solid stationary phase, bringing the separated components with it.

2024年1月5日 · Choosing the right chromatographic column for High-Performance Liquid Chromatography (HPLC) is crucial for achieving successful separation of your analytes. Here’s a guide to help you make the best choice:

Chromatography columns of different types are used in both gas and liquid chromatography: Liquid chromatography: Traditional chromatography columns were made of glass. Modern columns are mostly made of borosilicate glass, acrylic glass or stainless steel.

A comprehensive selection of HPLC, UHPLC and SFC column chemistries on traditional silica ensure that you have the optimum column for your application. High performance columns, with lasting durability, are readily available for the analysis of small molecules up …
