what is high pressure liquid chromatography?
High pressure liquid chromatography (HPLC) was developed in the mid-1970s. It differs from other chromatographic techniques in that the liquid is pumped through a short packed column under pressure, instead of relying only on gravity. Previ... Read More »

What is high pressure liquid chromatography in chemistry?
It is a modified form of column chromatography, in which a pump forces solvent through a column under high pressure (up to ca.400 atm) rather than simply allowing the solvent to flow slowly through the column under gravity. The advantages a... Read More »
