摘要
本文建立了测定食品包装材料中甲醛的衍生气相色谱法。方法的检出限达到0．01ng／mL。本法在0～0．8pg／mL范围内有较好的线性关系，相关系数R=0.9999，平均回收率为99．89／6～100．2％。
Gas chromatography with derivation was described for the determination of trace formaldehyde in food packing material. The detection limit was 0.01 ng/mL,which shows excellent sensitivity. A good linear range of 0-0.8 μg/mL was obtained with a regression coefficient of 0. 9999. The recoveris were 99. 8%-100. 2%.
