HPLC column stability is a critical factor. This note describes how the Agilent Poroshell HPH-C18 column performed brilliantly in an elevated pH mobile phases such as ammonium bicarbonate buffer.

A novel approach to enhancing the selectivity of ionizable compounds using superficially porous particles that are stable in a wider pH range is reported here.

The most significant recent advancement in liquid chromatography (LC) column technology is the new generation of superficially porous silica particles.

Beta blockers can be abused in sports involving little physical activity, such as archery, to reduce cardiac contraction, heart rate, and coronary blood flow.

The costs associated with pharmaceutical testing are considerable, and many lab managers are seeking ways to reduce costs by reducing solvent usage and improving productivity while still using the LC instruments in their lab.

A new phenylhexyl bonded phase provides an alternative selectivity for optimizing HPLC method. This also applies when different types of phenyl bonded phases are compared.
