Fordele

Overlegen fleksibilitet

Afhængigt af din applikation kan du bruge enhver detekteringsmetode med dit Metrohm IC system. Hver detektionsmetode har sine særlige fordele med hensyn til selektivitet og følsomhed.

Oversigt over detektorerne til Metrohm IC
Detektor mulighed	Fordele	Typiske anvendelser
Konduktivitetsdetektion	Fordele: Universal detektor til bredt anvendelsesområde Vedligeholdelsesfri Ikke-destruktiv detektion	Applikationer: Anioner, kationer, aminer (Metrohm Suppressor Modul tilgængeligt for mere følsom analyse)
UV/VIS-detektion	Fordele: Enkel kvantificering af UV- og VIS-aktive stoffer på tværs af hele UV/VIS-området Maksimal ydeevne ved fleksible indstillinger (bølgelængde, lamper, målekanaler) Kan opgraderes af iReactor til præ- og postkolonne-derivatisering Meget specifik og følsom, hvilket gør selv detektering på lavt niveau mulig	Applikationer: Direkte UV/VIS-detektion: nitrogen- og svovlforbindelser, halogener, organiske stoffer Med post-kolonne derivatisering: overgangsmetaller, oxyanioner som bromat og kromat i meget lave koncentrationer, aminosyrer, ammonium mv. Med præ-kolonne derivatisering: kompleksdannende midler som EDTA, NTA, PBTC
Amperometrisk detektion	Fordele: Bestemmelse af elektroaktive, dvs. oxiderbare eller reducerbare forbindelser. Høj selektivitet og følsomhed til bestemmelse af koncentrationer ned til ng/L området.	Applikationer: Kulhydrater Sukkeralkoholer af alle slags Mange anioner (f.eks. cyanid, sulfid, iodid, bromid) Mange kationer (f.eks. aminer, aromatiske aminosyrer) Organiske stoffer (f.eks. phenoler, katekolaminer, vitaminer)
Kombineret massedetektorer	Fordele: Høj sensitivitet og specificitet Mulighed for samtidig analyse Peak verifikation og identifikation	Applikationer: Specifikation af (spor)metaller og metaloider (As, Hg, Se; IC-ICP/MS) Kvantificering og profilering for kulhydrater (IC-MS, IC-MS/MS) Organiske molekyler, fx aminer (IC-MS, IC-MS/MS) Pesticider, fx glyphosat, AMPA (IC-MS, IC-MS/MS) Halogener og halogenerede forbindelser, fx perklorat, bromat, halogeneddikesyrer (IC-MS, IC-MS/MS)
