HYSphere

Various highly crosslinked polymers, with slightly different properties, such as Envi-Chrom P, Lichrolut EN, Isolute ENV or HYSphere-1, have been applied in environmental analysis, mainly for polar compounds. For phenol, for instance, which is a polar compound, the recoveries (%) when 100 ml of sample was analysed were 5, 16 and 6 for PLRP-s, Envi-Chrom P and Lichrolut EN, respectively (70). [Pg.357]

Nonpolar silica sorbents such as C18 have been used extensively (4). Elian and Hackett (19) reported using a novel fluorinated SPE sorbent for isolation of THC and THC-COOH from whole blood. In a totally automated SPE method Hysphere C8-EC extraction columns were used (16-18, 21), which allowed the direct introduction of extracted cannabinoids into the LC column. [Pg.76]
