Super Lowest Price Plastic Household Products - GCB PSA SPE – BM Life Science

 

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.

Application
Soil;Water;Body fluids(plasma/urine etc.);Food
Typical Applications:
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.
