B&M Carb-GCB (graphite-carbon black)/PSA (ethylene diamine – n-propyl) double SPE composite column has the same retention capacity as GCB/NH2, which is suitable for the purification of samples of pesticide residue detection. PSA has more a secondary amine than NH2, so the ion exchange capacity is larger and can be used as a complexation ligand for some metal ions, providing a different selectivity than GCB/NH2.

|Carb – GCB/PSA is used to remove the pigment in the food system, sterol, fatty acids and organic acids, etc.|
|especially suitable for more pesticide residues in food detection,including fruits, vegetables, meat, aquatic|
|products, grains, and dairy products, etc.The effect of PSA removing fatty acids (including oleic acid, palmitate,|
|linoleic acid, etc.) can be as high as 99%, which greatly reduces the matrix effect in GC analysis.|
