What is HPLC (High Performance Liquid Chromatography)

Web23 de jun. de 2014 · The most commonly used method is known as reversed-phase (RP-HPLC) and this is what I describe here. In this mode, compounds are separated starting with the most polar, and ending with the apolar compounds. For all modes, a high-powered pump moves the sample and the mobile phase through the column. A typical run can take … WebAbstract. Reversed-phase high-performance liquid chromatography (RP-HPLC) involves the separation of molecules on the basis of hydrophobicity. The separation depends on the hydrophobic binding of the solute molecule from the mobile phase to the immobilized hydrophobic ligands attached to the stationary phase, i.e., the sorbent. home improvement store northridge ca

WebThe sample to be analyzed is introduced in the flow path by an autosampler. Typically, the flow rate in most HPLC’s is between 0.05 – 2 mL/min. The pressure in the system depends mostly on the particle size of the stationary phase, the column length and flow rate. Typical pressures in HPLC are from 100 to 400 bar. WebVoid volume. In nearly all modes of HPLC, some form of selective retention by the stationary phase is required for column resolution. In order to know whether a compound is retained, one must calculate the column void volume, V 0, by measuring the retention time for an unretained solute at a given flow rate..
