Abstract
A device for trapping at least one chromatography peak of a chromatography flow comprises at least one trapping column, an inlet capillary for leading the chromatography flow into the trapping column and an outlet capillary departing from the trapping column. A plurality of trapping columns are provided on a column carrier wherein the trapping columns are separately and selectively connectable to and/or removable from the inlet and outlet capillary.
Claims16
A device for trapping at least one chromatography peak of a chromatography flow in a system with a LC-device and a NMR-detector, wherein said trapping device is connected to said LC-device and to said NMR-detector, said trapping device comprising:
- a plurality of trapping columns arranged on a column carrier;
- an inlet capillary and an outlet capillary, said trapping columns being separately and selectively connectable to said inlet and said outlet capillary;
- said column carrier having at least a first connecting capillary connected to said inlet capillary and a second connecting capillary connected to said outlet capillary, and each of said trapping columns having at least a first capillary connectable to said first connecting capillary and a second capillary connectable to said second connecting capillary in a sealed fashion, and first connecting capillary being detachable from said inlet capillary and said second capillary being detachable from said outlet capillary,
- wherein said column carrier is removable as a whole with said trapping columns mounted thereon from said trapping device.
