“…152,153 These procedures did not include stabilizing compounds (i.e., HAH, TMPD, p-TSA) and eliminated the dichloromethane partitioning as well. Storey et al 154 developed a procedure to extract fish with McIlvaine buffer (pH 4.5), EDTA, p-TSA, and TMPD for an LC-MS/MS residue screening method without additional liquid-or solid-phase clean-up. Van de Riet et al 155 developed an extraction procedure to permit sensitive LC-MS/MS determination based on a simple tissue extraction using acetonitrile and perchloric acid, with dichloromethane and SPE clean-up.…”
