Professor Moinuddin Qureshi was recently honored for a paper that continues to influence memory chip efficiency nearly a ...

Explore how in-line Raman and NIR spectroscopy, combined with chemometrics, enables real-time reaction monitoring for better ...

LCGC International interviewed Bob Pirok from the University of Amsterdam, Netherlands to discuss strategies for enhancing ...

High-performance liquid chromatography (HPLC) is an analytical chemistry technique used to separate liquid mixtures of compounds or analytes. The method employs a liquid "mobile phase" to transport ...

Retention time is an important parameter in chemical analysis, particularly in chromatography, as it enables the identification and quantification of compounds based on their unique properties. This ...

3. Calculate the retention factor for each spot using the formula: RF = Rf_sample / Rf_solvent Calculating Retention Factor in Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) ...

HPLC technology has the following main advantages: the application of extremely fine particles (generally less than 10 μm), regular and uniform stationary phase, low mass transfer impedance, high ...

Retention time repeatability was less than 0.01 min, and peak area %RSDs were less than 0.5% for all analytes. Figure 5 shows the calibration results for all six isoflavone compounds over the range of ...

In the case of reversed phase chromatography, less polar analytes will preferentially partition into the non-polar stationary phase and have a longer retention time. The data acquisition system ...
