Investigation of peak purity failure during HPLC method validation led to discovery of a co-eluting impurity under the main peak. Spectral analysis, including three-dimensional modelling, was used to ...

An interview with Dr. Michael Dong, about his upcoming talk at Pittcon. Why are stability-indicating methods important in pharmaceutical analysis? The stability-indicating assay is perhaps the single ...

When conducting reproducible and interference-free analysis by liquid chromatography, the purity of the solvents used, particularly the purity of water, is crucial for the sensitivity of this method, ...

This study developed a High-Performance Liquid Chromatography (HPLC) method for the analysis of major withanolides in ashwagandha root and commercially available supplements. System suitability ...

There are a few scenarios where analytical procedures might need to be transferred between HPLC instruments: 1) Method transfer to new equipment in the same lab, perhaps to a different vendor or a ...

Analysts interested in organic molecules like dissolved organic matter or pharmaceuticals should consider quantifying organic molecules with the High Performance Liquid Chromatography (HPLC) ...

This course is a classroom-based course covering all the practical theory about liquid chromatography and its related techniques including liquid chromatography-mass spectrometry. This course is ...
