| Abstract: | The methanol content in various wines was determined by multidimensional gas chromatography(MDGC).The wine samples were directly injected by autosampler.The methanol was successively separated by nonpolar RTX-5ms and polar HP-INNOWax.The content was quantitatively analyzed by mass spectrometry in SIM mode.The calibration curves showed good linearity in the range of 1-10000 mg/L.The detection limit is 1 mg/L.The recoveries were 91.3%-101.9% with a relative standard deviation of 4.5%-8.6% at 5,50,250,400 and ... |
