High-performance liquid chromatography (HPLC) stands as a cornerstone in the world of analytical chemistry, providing unparalleled precision and efficiency in separating complex mixtures.  The heart of HPLC’s efficacy lies not just in the sophisticated machinery but significantly in the column packing, a seemingly minute yet… Read More »How Does HPLC Column Packing Affect Column Performance

Preparative HPLC is often associated with large capacity columns and high flow rates. However, it is not the size of the equipment and the amount of mobile phase consumed by the system that determines preparative HPLC but rather the purpose of the separation. Unlike the… Read More »Main use and technical characteristics of the preparative liquid phase

As we know , Maintaining a clean mobile phase from start to finish is crucial for reliable HPLC analysis.  High-quality filters play a vital role in filtering out impurities before they reach the sensitive separation stage in the column, ensuring consistently robust methods and excellent… Read More »Filters and Filtration in Liquid Chromatography System

What Do You Mean for Ghost Peaks?  When doing the gradient elution of liquid chromatography reversed-phase system, sometimes we will encounter the situation that the instrument does not feed the sample but also has the peak, affecting the quantitative results.  It can also make the… Read More »3 Reasons for Ghost Peaks and Solutions

In liquid chromatography (LC), “volume” can have several different meanings depending on the context. Here are three main interpretations: 1. Void volume (Vm): This refers to the total volume of liquid (mobile phase) contained within the column. It essentially represents the space not occupied by… Read More »What is the meaning of “volume” in liquid chromatography

High-performance liquid chromatography is an important branch of chromatography.
