Vanquish Horizon UHPLC Systems allow you to run smaller particles and column dimensions with confidence Achieve your next ...
Commercially available packed microbore columns have been used to demonstrate the potential of microbore high performance liquid chromatography (micro-LC) systems. The necessity of optimizing the chromatographic system for micro-LC is demonstrated using sulfa drugs and antibiotic standards, and some of ...
Ultra high performance liquid chromatography (UHPLC) arose from the desire to increase sensitivity, resolution, and efficiency over traditional HPLC parameters in order to drive modern separations applications. To accommodate new technologies with smaller bead diameters and shorter column lengths, systems c...
GLOSSARY OF LIQUID-PHASE SEPARATION TERMS The first glossary of common and not-so-common terms and buzzwords for reference to high performance liquid chromatography (HPLC) columns and column technology was published in 1988 (1). It is time for an update because ? many new terms have arisen ...
(LC/MS and LC/MS/MS) and is routinely used for quantitative analysis in biological samples such as blood, urine and other body fluids. HPLC consists of using a liquid mobile phase to pass under high pressure a mixture of analytes extracted from the sample through a column containing the ...

The first plenary lecture was by Professor Gert Desmet of Vrije U. Brussels on “evolution in column making,” which I missed. I happened to miss all four plenary lectures due to schedule conflicts. 第一场全体会议由布鲁塞尔大学的Gert Desmet教授主讲“色谱柱制作的进化”,我错过了这个讲座。由于日...
The first extract was subjected to RP-HPLC on a Phenyl 5PW-RP column with 100-nm pores. The smallest proteins, F2 (13–15 kDa) and M (38 kDa), were both eluted as a sharp peak at 32.5 and 40% organic solvent concentration, respectively (see Fig. 12.4). This difference also shows...
Methods presented are geometrically scaled as column volumes are adjusted, preserving chromatographic integrity per the guidelines found in USP General Chapter 621. These concepts will be demonstrated by transferring existing USP methods...
