Title: Microsoft PowerPoint - HPLC Column Troubleshooting_012909 [Compatibility Mode] Author: Owner Created Date: 1/28/2009 10:58:41 PM These new HPLC instruments could develop up to 6,000 psi [400 bar] of pressure, and incorporated improved injectors, detectors, and columns. HPLC really began to take hold in the mid-to late-1970s. With continued advances in performance during this time [smaller particles, even higher pressure], the acronym HPLC remained the same, but the name was changed to high performance liquid … View and Download PowerPoint Presentations on Preparative Hplc PPT.

(2001) Major Separation Modes of HPLC A Review There are four major separation modes that are used to separate most compounds: ¾Reversed-phase chromatography (most popular) ¾Normal-phase and adsorption chromatography ¾Ion exchange chromatography ¾Size exclusion chromatography ….Let’s look briefly at each mode Solvent and reagent - HPLC grade Mixed mobile phase or buffer Volume contraction effects – mixing water-miscible solvents pH adjustment, addition of non -ionic additives Filter immediately before use Pore size 0.45um to 0.8um Types of filter: Nylon – hydrophilic (high content of water/aqueous) PTFE – hydrophobic, chemically resistant HPLC seminar 1. Introduction High Performance Liquid Chromatography (HPLC) is one mode of chromatography, the most widely used analytical technique.

In modern HPLC the columns andIn modern HPLC the columns and packingspackings are, in general, highly refined, are, in general, highly refined, High performance liquid chromatography (HPLC) is basically a highly improved form of column liquid chromatography.
HPLC detector. One approach is derivatization, which enhances the detection sensitivity and selectivity for the target component. Many special reagents and techniques have been developed to improve derivatization. In this article, we will discuss the general derivatization methods used in HPLC.
