Determination of tertiary butyl hydroquinone in edible oil by gas chromatography using gel penetrating chromatogram
A GC method for determination of Tertiary butyl hydroquinone(TBHQ) in edible oil was developed.The linear range for TBHQ was 1～1000mg/L with a correlation of 1.The detection limit for TBHQ was 0.002mg/mL.The recovery range for TBHQ was 87.2%～95.1%,and the standard deviation range was no more than 6.95%.
