Du sökte efter: Kromatografikolonn
Kromatografikolonner separerar molekyler under gas- eller vätskemetoder. Färdigpackade kolonner finns med olika stationärfaser och resiner. De färdigpackade kolonnerna står emot temperatur- och tryckvariationer som uppstår när mobilfasen trycks genom kolonnen. Det finns kromatografikolonner för preparativa och analytiska metoder för att separera komponenter baserad på individuell polaritet, sammansättning och storlek.

Vätske-vätskeextraktion, Extrelut® NT
Supplier: Merck
EXtrelut® NT is a specially processed, inert, wide pore kieselguhr with a high pore volume. It has been used for quite some time within research, for the sample preparation of urine, whole blood, plasma and other biological matrices. Other applications include environmental and residue testing such as analysis of industrial, domestic and wastewater. EXtrelut® NT is supplied either pre-packed in cartridges or as a loose sorbent. EXtrelut® NT simplifies liquid-liquid extraction by replacing separation funnels. Using a single step is more efficient, saves solvent, as well as material and time, in contrast to classic funnel separation. The aqueous sample is simply applied to the EXtrelut® NT sorbent. It distributes itself over the chemically-inert matrix so acting as a stationary phase. Subsequently, elution takes place using organic solvents that are non miscible with water. All the lipophilic substances are extracted from the aqueous into the organic phase.
