and online pre-processing is column switching (CS). As early as the 1970s, HPLC column switching technology was applied with the development of dead volume switching valves. However, it was not until the 1990s that with the increasing emphasis on the analysis of complex...
Our company offers several types of polymeric based columns for the analysis of carbohydrates, organic acids, and alcohols. Please contact us in regards to your specific separation needs. We will help you choose a replacement column for your application, or recommend a column for a new assay. ...
and larger 3.5/5 μm HPLC columns Designed to withstand higher pressures of 9,000 psi (4.6 mm ID) and 18,000 psi (2.1 and 3.0 mm ID) Select column length (30, 50, 75, 100, and 150 mm) for the correct balance between resolution and throughput High T hroughput....
(A) by direct connection of injector to detector using a "zero-length" column; (B) by measuring the plate number N as a function of capacity ratio, k′; (C) by placing a 2m × 100 µ m bore straight open tube between injector and detector, and subtracting the contribution from the...
(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 ...
However, nitrogen evaporators require precise manufacturing and proper setup to function optimally. Effective integration and operation of these systems can enhance lab productivity while ensuring compliance with regulatory standards for drinking water and other sample types.

Relegation chromatography is a preliminary fashion in which a sample is placed onto the head of the column and is also displaced by a solute that's further explosively adsorbed than the factors of the original admixture. As a result, the factors are resolved into successive blockish zones of ...
Agilent A-Line Quick Connect Fittings The fast, easy way to more predictable results Poorly connected flow path fittings are one of the top reasons for peak tailing, peak broadening, split peaks, and carryover. That's because dead volume or micro-leakage can cause extra-column volume, which ...
HPLC (High Performance Liquid Chromatography) and LCMS (Liquid Chromatography-Mass Spectrometry) are analytical techniques used to separate, identify, and quantify compounds within a mixture. HPLC focuses on the separation of compounds based on their interaction with the column's stationary phase and th...
