GOOD LABORATORY PRACTICE for HPLC I- Preparation of solvents Correct solvent preparation is very important. It can save vast amounts of time spent troubleshooting spurious peaks, baseline noise, etc I-1. Quality All reagents and solvents should be of the highest quality. HPLC grade

HPLC bottles hold the mobile phase of high-performance liquid chromatography, often acting as a reservoir for the solvent. The bottles are made from borosilicate glass or highly durable plastics such as Teflon. Special caps prevent particulate matter from contaminating the mobile phase and possible spills.

However, the similarities between the two end there and the differences between HPLC and UPLC begin. UPLC operates at considerably high pressures of 15,000 psi (psi, in this case, stands for Pounds per square inch and is a unit of pressure), while HPLC operates at relatively lower pressures of 500-6000 psi.

HPLC Solvent Management Waters HPLC pumps enable you to customize HPLC Systems to accommodate your solvent delivery needs, whether for isocratic or gradient, analytical or preparative.

media bottles to be used as an HPLC reservoir. Caps have two holes to accomodate 1/8" tubing and one hole that accepts a standard luer inner joint. Caps are made from polypropylene and the inserts are made from Tefzel.

HPLC injection is a technique used to load the sample into the HPLC system. This process is done using a specially designed injection system which is a separate and prominent part of the HPLC system. The most popular injector is the rheodyne injector. The injection is done manually by an external syringe or autoinjector.
