The objectives of this presentation are to describe the principles of chromatography, to introduce the fundamental concepts of high performance liquid chromatography hplc, and to discuss the. Following are explanations of the separation mechanisms commonly used in hplc. Example hplc chromatogram mixture of perfume and water1 the xaxis is labeled with a time unit, typically minutes, and the yaxis can be a variety of things depending on the specifics of each experiment. Reversed phase, hydrophilic interaction and normal phase chromatography columns polymerbased columns for reversed phase chromatography odp2 hp. Many types of hplc detectors exist, each of which has some valuable. Learn how hplc combination with fluorescence detection can help you find the answers to your toughest analytical problems. Hplc chromatography lecture this lecture explains about the hplc chromatography technique in a nutshell by suman bhattacharjee. High pressure liquid chromatographyhplc is a type of column chromatography generally used in biochemistry and analysis of active compounds to identify, quantify and. In an hplc system the detector is the component responsible for turning a physical or chemical attribute into a measureable signal corresponding to concentration or identity. The obtained information is especially useful for compound structure identification. Highperformance liquid chromatography hplc methods via evaporative light scattering els and refractive index ri detectors are used by the local palm oil industry to monitor the tag profiles.

Ultravioletvisible spectroscopic detectorsuv detector vis detector. They are usually very cheap, in the nowadays you probably wont be able to find that type of the detector on the market. Hplc instrument but it takes the signal from the detector and uses it to determine the time of elution retention time of the sample components qualitative analysis and the amount of sample quantitative analysis. Chromatography is a technique to separate mixtures of substances into their components on the basis of their molecular structure and molecular composition.

Here we will shortly explain a two type of cal ibration. Working of these detectors involve different principles such as optical. Calibration of an hplc method is ne cessary to give quantitative results. The ri detector is one of the few universal detector available in lc. Introduction to the theory of hplc basic principles of hplc 174 hplc high performance liquid chromatography depends on interaction of sample analytes with the stationary phase packing and the mobile phase to effect a separation. For example, if you were using a uvvis element as a detector, the yaxis would be labeled absorbance. Reversedphase chromatography is the most commonly used hplc separation mode. This involves a stationary phase a solid, or a liquid supported on a solid and a mobile phase a liquid or a gas. Hplc detectors types comparison principles pdf ppt.
