Carb-GCB/PSA SPE Cartridge

Finetech® Carb-GCB/PSA is a sorbent similar to Carb-GCB/NH₂ and suitable for cleaning samples up in multi-residual 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/NH₂.

​

◆ Features:

​

• Ultra thin frits between two sorbent layers promises uniform flow

• Capable of removing interference as thoroughly as possible

• Higher capability than Carb-GCB/NH2
