There are many SPE cartridge packing types: C18, C8, NH2, CN, silica gel, alumina, Florisil, diatomaceous earth, polyamide, activated carbon, Diol (diol based), graphitized carbon black, XAD-2, GDX- 403, HLB, graphitized carbon black/amino filler, macroporous adsorption resin, and the like.
HAWACH is able to provide SPE cartridge and cartridge with different sorbents.
Format: 100mg/1ml, 60mg/3ml, 200mg/3ml, 250mg/3ml, 500ml/3ml, 500mg/6ml, 1000mg/6ml, 2g/6ml, 2g/12ml.
Though C8 is similar to C18, it has short carbon chain with week reservation than C18 to non-polar compound. If the analyte has too strong reservation on C18, then C8 can be the choice. In the meantime, as C8 has shorter carbon chain, it can’t cover the Residual Silanol Groups on the surface of silica gel, as it has stronger reservation than C18 to polar compound.
HAWACH can supply SPE cartridge adapter too.
The simplest SPE can be done manually, by attaching a syringe to the upper end of the SPE and extruding the liquid from the extraction cartridge by squeezing the syringe. Alternatively, a batch sample may be subjected to a SPE operation using a positive pressure or negative pressure SPE apparatus. With the development of technology and the increasing samples, more and more analytical laboratories began to use automated SPE, especially multi-channel SPE to process batch samples.
