High Performance Liquid Chromatography, or HPLC, is the most common analytical separation tool and is used in many aspects of drug manufacture and research. HPLC is used for: 1. Qualitative and quantitative analysis of unknown mixtures – determining what is there, and how much. 2. Separation of mixtures for later analysis –preparative HPLC.

recommended for HPLC use. Ultra pure HPLC water (18M Ω resistivity) is generated by passing deionized water through an ion exchange bed. Modern water purification instruments use this mechanism to produce water of suitable quality in high volumes. Alternately, HPLC grade water can be purchased from solvent suppliers. I-2. Buffers
HPLC Standard Operating Procedure Last Revised March, 3, 2016 This document is intended to be a guide for operating the Garner Lab’s HPLC systems and is only intended to provide instructions for users who are already generally familiar with HPLC operation. If

HPLC is widely used for the analysis of constituents of a pharmaceutical actives, drug products, pesticides, and countless other substances. In UPLC, or ultra-high performance liquid chromatography, column particle size of less than 2um can be used. This allows for better separation than the typical particle size of 5um that are used in HPLC.
labor intensive to prepare; please use no more than necessary! b. Stock standard solutions. Three standard solutions, each containing one of the analytes, will be provided. These solutions will contain a) caffeine (0.4 mg/mL), b) aspartame (6 mg/mL), and c) benzoate (0.7 mg/mL). You should record the exact concentration of each analyte. 2.
Insert HPLC mobile phase supply tubing into the bottles; remaining tubes must be also dipped in one of the bottles (e.g., solution C) and primed even if they are not required for mixing. During the run, mix the mobile phase solutions as 6% solvent A, 74% solvent B and 20% solvent C to achieve final solution of 50 mM sodium phosphate buffer (pH
High-Performance Liquid Chromatography (HPLC) is a high-resolution technique for separation and quantitation of range of small molecules, biomolecules, and peptides. Ultra-high performance (UHPLC) systems are capable of increased pressure and are designed for increased resolution and performance. Platform availability ranges from all-in-one to
Its earlier name was High Pressure Liquid Chromatography because it involved use of liquid mobile phase requiring higher pressures than gases used in Gas Chromatography. The technique has found immense scope of applications in both academic and industrial laboratories requiring identification and quantification of mixtures of organic compounds.
Caution: opening the inlet end, and more so opening the outlet end, can permanently damage the packing bed. Before opening columns, consult the manufacturer’s literature. (Never open either end of a resin-filled column). Use the following procedure to open a column. Disconnect the column from the system.
