RP-HPLC operates on the principle of hydrophobic interactions, which originates from the high symmetry in the dipolar water structure and plays the most important role in all processes in life science. RP-HPLC allows the measurement of these interactive forces. The binding of the analyte to the stationary phase is proportional to the contact surface area around the non-polar segment of the analyte molecule upon association with the ligand on the stationary phase. Thi HPLC works following the basic principle of thin layer chromatography or column chromatography, where it has a stationary phase (solid like silica gel) and a mobile phase (liquid or gas). The mobile phase flows through the stationary phase and carries the components of the mixture with it. Different components travel at different rates So what are the principles of HPLC? Only by understanding the principles will we be able to understand how to efficiently separate materials. In HPLC, the stationary phase must be prepared. The stationary phase is the column, a small cylinder. As the solution passes through the column, it allows the materials to be separated Hochleistungsflüssigkeitschromatographie - in den Anfangszeiten dieser Technik auch Hochdruckflüssigchromatographie genannt - ist eine analytische Methode in der Chemie. Die HPLC ist ein Flüssigchromatographie-Verfahren, mit dem man nicht nur Substanzen trennt, sondern diese auch über Standards identifizieren und quantifizieren kann. Im Unterschied zur Gaschromatographie, die eine sehr gute Trennmethode für verdampfbare Stoffe ist, können mittels HPLC auch nicht.

High-Performance Thin-Layer Chromatography (HPTLC) Principle The HPTLC works on the same principles as TLC such as the principle of separation is adsorption. The mobile phase or solvent flows through the capillary action. The analytes move according to their affinities towards the stationary phase (adsorbent) methods used in HPLC. Two methods of derivatization are used in HPLC: pre-column derivatization and post-column derivatization. The difference between these methods is that the derivatization reaction occurs before the column with the pre-column method and after the column with the post-column method. The features of each method are discussed below High Performance Liquid Chromatography (HPLC) An analytical separation technique that involves the high-pressure flow of a liquid through a column that contains the stationary phase.

In view of its widespread use and applications, high-performance liquid chro-matography (HPLC) will be discussed in a separate chapter (Chap. 28). The general principles of extrac Normal-Phase HPLC In his separations of plant extracts, Tswett was successful using a polar stationary phase [chalk in a glass column; see Figure A] with a much less polar [non-polar] mobile phase. This classical mode of chromatography became known as normal phase. Figure S-1: Normal-Phase Chromatography. Figure S-1 represents a normal-phase chromatographic separation of our three-dye test. (HPLC) uses micron-size particles for stationary phases (10 µm or less). However, such fine column packings results in high flow resistance which makes it necessary to use pumps to force analyte through a column of the stationary phase. The main advantage of the HPLC over the gravity liquid chromatography is that samples can be separated more quickly. It also allows separation of samples.
