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 ...

High Performance Liquid Chromatography (HPLC) is an analytical procedure for separation, identification and quantification of substances using liquid chromatography (LC). The mixture for separation is ...

The authors discuss the approach taken to develop a new calibration approach, its associated protocols, and how it can be used to calculate data. The use of open-access high-performance liquid ...

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 ...

High performance liquid chromatography (HPLC) has become an essential technique in pharmaceutical analysis for the separation, identification, and quantification of pharmaceuticals. Due to its high ...

Koi Peptides has launched BPC-157, a synthetic pentadecapeptide, as a research-use-only reference compound for laboratory use. Each batch is characterized by HPLC for purity and by mass spectrometry ...

Synthetic oligonucleotides have been used as critical research reagents in the biotechnology industry since its beginning in the 1970s. Their increasing use first led to the formation of many core ...

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, ...
