liquid column chromatography ultra-performance liquid chromatography 2020-06-16T17:08:57Z An ultra-high pressure form of liquid column chromatography in which the solvent is forced through the column under high pressures of up to 1000 atmospheres (15,000 psi). Higher pressure and smaller column particle sizes of less than 2 um helps UPLC outperform HPLC. MMO:0000720 UHPLC UPLC measurement_method_ontology slaulede ultra high performance liquid chromatography
