SPE adsorbents (Bulk), CHROMABOND PSA
Packing material, adsorbents for SPE applications. Our PSA (propylsulfonic acid modified silica) is a very strong cation exchanger (capacity ~ 0.7 meq/g), contrary to the CHROMABOND SA phase no π-π interactions. Note - for QuEChERS application see "CHROMABOND Diamino or CHROMABOND QuEChERS".
