SPE Products
Bonded Silica phases:
-Spherical particles with average size of 40-60μm, and pore size: 60Å/120Å
Monolayer bonding —Absorption / Desorption is quickly.
-C18, C18-N, C8, CN, NH2, COOH, Silica, PSA, PRS, SCX, SAX, Diol
Unique: AQ-C18; Amide ; PEG/C18
Polymer Based Phases:
- PEP (polar enhanced polymer); pyrrolidone modified PS-- HLB
- PCX sulfonic acid modified strong cation exchanger-- MCX
- PAX tertiary amine modified strong anion exchanger--MAX
- PWCX weak cation exchanger
- PWAX weak anion exchanger –WAX
- PEP-2, unique and more convenient than HLB; no need to adjust pH of samples
