Availability of the different types of columns, operating parameters, mobile phase composition, diluent and pH values make it critical to develop an analytical method. A good analytical method should be simple, used column, mobile phase and buffer should be common. It can be done easily step by step. Types of HPLC. There are many ways to classify liquid column chromatography. If this classification is based on the nature of the stationary phase and the separation process, three modes can be specified.

Choosing Right Column for Reverse Phase HPLC Separations 1. Pore Size Choose a column packing with small pore size (60-80Å) if the solute molecular weight is less than about 2000 - 4000 Daltons. Otherwise, use a column packing with 300Å pore size. Figures 1 and 2 shows the effects of pore size on peak width and sample load. Note that the higher surface area, 80Å packing, tolerates higher HPLC Column Comparison Screening Study for Reversed Phase Columns Carmen T. Santasania, David S. Bell, and Tracy L.

The majority of chemists will begin with some type of C18 …

The mobile phase used in HPLC is a liquid whereas it is a gas in case of Gas chromatography. Due to the higher density and viscosity of liquids a pump becomes necessary to drive the liquid through the HPLC column and as a result back pressure are high. HPLC Column Classification Brian Bidlingmeyer,*Agilent; Chung Chow Chan,{Eli Lilly and Company; (HPLC) column type was introduced for the first time in theFourth Supplementto USP XIX in 1978.

The columns are different for HPLC and UHPLC, with UHPLC columns having much smaller particles, and being are shorter and smaller in diameter than HPLC columns.

In addition, there is a discussion of its applicability to be used with conventional HPLC instruments. Finally, it outlines some of its recent applications in biological and pharmaceutical field. Keywords: High pressure liquid chromatography, Core-shell particle columns, Sub-2 µm particle columns, Monolithic columns, Back pressure. As columns had different lengths, theoretical plate number was not sufficient for correct comparison. It could be seen, that Acquity UPLC analytical system had comparable efficiency for most analyses as commonly used HPLC. In case of Estrogel gel and Hydrocortison cream analysis the efficiency was even much better (about five times, about 3–7 times, respectively) in case of UPLC system.
