Use fresh sample or standard to confirm sample as source of problem. If some or all peaks are still smaller than expected, replace column. If new column improves analysis, try to restore the old column, following appropriate procedure . If performance does not improve, discard old column. Check system for loose fittings.
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.
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

Oct 13, 2016 · Recently, Ade Kujore (Cecil Instruments), Tracie Brombos (GenTech Scientific), and I were asked by Angelo De Palma, a well-respected writer for Lab Manager magazine, to contribute to an article about maintaining and caring for your laboratory instruments. Here are my tips and best practices for column and HPLC, UHLPC, and UPLC system maintenance.
• Small opening requires Micro-Inserts with a diameter of 5mm • While maintaining the standard outer dimensions the internal volumes of these vials range from below 300μL to 2mL • Where levels of inorganic ions have to be kept to an absolute minimum the use of plastics may be preferred to the more conventional glass vials
The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom
Qualitative HPLC Analysis Before you read this supplement, you should have an understanding of liquid chromatography and UV absorbance detection. See your lecture notes, your textbook and the SRIF backgound paper on HPLC. As you noted in the introductory lab sesssion, the HPLC system gives out two types of data images.
