The Selection Of SPE Cartridge

To select the appropriate SPE cartridge, we normally consider it from two aspects: the selection of adsorbent and specification of the cartridge. The use of appropriate adsorbent can achieve good separation between interfering substance and target component, and also meet the requirement of recovery. However, the mass of chemical compound which can be adsorbed by the adsorbent is limited, once the mass of the sample is too large, there can be overload which happens in the SPE cartridge, and therefore makes the target component directly go through the cartridge without being reserved.

Basically, we can select the adsorbent according to the properties of the target component and the substance. Moreover, for the concrete examples, we can also select the adsorbent which is based on the principle of “distinguish the target component and the main interferent”
