Ultra High Performance Liquid Chromatography (UHPLC)
UHPLC, Ultra-High-Performance Liquid Chromatography is similar to HPLC, in that it is a technique used to separate different constituents of a compound. Used predominately to identify, quantify and separate components of a mixture by using high pressure to push solvents through the column. In UHPLC, which is nothing but ultra-high performance liquid chromatography, particle sizes less than 2um can be used, providing better separation than with HPLC where particle size is limited to 5um. Another distinction, the pump pressure in HPLC is 40MPa, in UHPLC, this pressure can go up to 100MPa making this technique very efficient with fast analysis and higher resolution.
