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 ...

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 ...

This paper describes a unique Prep-rP-HPLC technique that uses a C-18/C-8 derivatized silica coated with a hydrophobic quaternary ammonium salt or quaternary phosphonium salt that acts as an ...
