Anti-clogging Frits

Our specially designed frits can replace the original cartridge frit or simply be added on the top to prevent clogging. Since this multi-layer frit is less adsorptive to very hydrophobic analytes (such as PAHs and PCBs) than regular frits, the elution volume for collection may be reduced considerably if the original frit is replaced with the multi-layer frit. PromoChrom provides a tool kit to make the replacement easy.

Cartridge 1 is with original frit.

Cartridge 2 has a multi-layer frit on top of the original frit.

Cartridge 3 has the original frit replaced with the multi-layer frit.

 

Shown here are samples with considerable amounts of particulates extracted on 6 mL C18 cartridges. After loading 100 mL of sample, cartridge 1 is blocked significantly, whereas cartridges 2 and 3 are still working as normal.
