Pumps used in UHPLC or UPLC systems operate above 6,000 PSI, which is typically the upper limit of conventional HPLCs. The technique was first patented in 2004 by Waters with the trademarked acronym “UPLC.”</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31341388"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14084537"> <skos:prefLabel xml:lang="es">ultra high performance liquid chromatography (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9847134"> <skos:prefLabel xml:lang="ca">ultra high performance liquid chromatography (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:40:22</dct:created>  </skos:Concept></rdf:RDF>
