HPLC: High Pressure Liquid Chromatography 2013 Chem 413 Introduction Chromatography can be described as a mass transfer process involving adsorption using a nonpolar stationary phase and a mobile polar phase titrating through the column. Biotic components: The biotic components are the organic compounds and also known as living component of an ecosystem. The data analysis was done using Empower 2 software. The difference between traditional LC and HPLC is that the solvent in LC travels by the force of gravity. The void volume of a system is usually determined by injecting an unretained standard (Uracil in RP-HPLC) that has no or very little retention on a particular phase. 3 Improving the Separation, 13 1. Practical HPLC Method Development [Snyder, Lloyd R. High-performance liquid chromatography, or HPLC, is used to separate both solid and liquid compounds and to reveal the differences in their interaction with a stationary phase. ) t g = gradient time (min. This phenomenon can also occur in a HPLC system where rough surfaces produce nucleation sites for bubble formation. In HPLC analysis the problems produced by bubble formation can largely be prevented, by degassing the mobile phase. Air bubbles can also modify the flow of mobile phase through the column due to the creation of dead volumes. Supercritical fluid chromatography (SFC) is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. Undergraduate laboratories continue increasing the use of instrumentation in teaching. However, the similarities in these liquid chromatography techniques end there, as UPLC (Ultra Performance Liquid Chromatography) operates at higher pressures (15,000 psi) and allows for lower particle sizes in columns, while HPLC (High Performance Liquid Chromatography) operates at lower pressures (max 500-6000 psi).
