SPE-HLB sorbents are produced with a special polymerization technique. It is corrresponding to Water Oasis HLB or Phenomenex Strata X. They are reverse phase sorbents wettable by water with balanced hydrophilicity and hydrophobicity capable of satisfying most solid phase extrction needs.
Monodisperse microspheres in SPE-HLB sorbents are made with outstanding ability to retain polar compounds. They are quite suitable for the isolation of compounds with none or medium polarity.
