Cleanup of samples in multiresidual pesticide analysis
Carb-GCB/NH 2 combines the merits of both Carb-GCB and NH 2 sorbents and is able to remove interfering compositions such as pigments, sterols and fatty acids in food samples, making it an effective packing for cleaning samples up in multiresidual pesticide analysis.
- Ultrathin frits between two sorbent layers promising uniform flow
- Capable of removing interferences as thoroughly as possible
