Summary
Type: SPE
Application #: 301770
Catalog#: 730107G - SPE Cartridges, Chromabond, Silica, 6ml, Glass, 2000mg, 30/pk
Detection: GC
Conditions: Column conditioning:
Heat column for 1 h at 140 °C to increase the activity and reproducibility.
After cooling to about 30 °C force or aspirate 5 ml n-pentane through the column.
Sample application:
Slowly pour 200 μl sample solution through the column
Elution: Elute with the following solvents (1 ml / min), collect 1 ml
fractions, concentrate in a stream of nitrogen and analyse by GC:
2 ml n-pentane: dead volume
4 ml n-pentane: aliphatics
8.5 ml 5 % CH2Cl2 / n-pentane: monoaromatics
5.0 ml 10 % CH2Cl2 / n-pentane: diaromatics
5.0 ml 60 % CH2Cl2 / n-pentane: polyaromatics
5.0 ml 25 % acetic acid / methanol: polar compounds
