Solid phase extraction cartridges                                       Back to main page

C18, C8, PSA, SAX, SCX are made of high purity silica. Its surface is specially modified to ensure high sample recovery and good reproducibility
Average particle diameter: 45 um       Average Pore Size: 60          Pore Volume: 0.8 cm2/g         Specific Surface Area: 480 m2/g

PEP cartridges use polymer based sorbents. The polymer is  polystyrene/divinylbenzene with vinyl prolidone. They have good adsorption for
for both polar and non polar compounds.  The pH range is 1-14. 
Average particle diameter: 35 um     Average Pore Size: 80          Pore Volume: 0.8 cm2/g         Specific Surface Area: 600 m2/g
