Cleanup of samples in multiresidual pesticide analysis


Carb-GCB/PSA is a sorbent similar to Carb-GCB/NH 2 and suitable for cleaning samples up in multiresidual pesticide analysis.

Due to its additional secondary amino groups, PSA has higher ion exchange capability and ability to chelate some metal ions, thus providing Carb-GCB/PSA with unique selectivity different from Carb-GCB/NH 2..



  • Ultrathin frit between two sorbent layers promising uniform flow
  • Capable of removing interferences as thoroughly as possible
  • Higher capability than Carb-GCB/NH2

Specifications for Carb-GCB:

Surface area: 100-250 m 2/g
Particle size: 100-300 mesh


Specifications for PSA:

Carbon content: 8%
Surface area: 500 m 2/g
Particle size: 50 - 75 μm
Pore size: 100 Å
