Jn. Leibowitz et al., DETERMINATION OF 6 COMMON PHTHALATE PLASTICIZERS IN GRAIN NEUTRAL SPIRITS AND VODKA, Journal of AOAC International, 78(3), 1995, pp. 730-735
Two direct sample injection methods using liquid chromatography (LC) a
nd gas chromatography coupled with mass spectrometry (GC/MS) were used
to determine phthalate residues in grain neutral spirits and vodka. S
ix reported phthalates were quantitated at concentrations as low as 20
mu g/L (20 ppb) with no sample preparation or sample enrichment.
