BS EN 16857:2017规定了软饮料中苯的测定方法，其他 饮料和基于蔬菜的婴儿食品，通过顶空气相色谱-质谱（HSGC）- MS）。该方法已在实验室间研究中得到验证，该研究通过分析 碳酸软饮料、静止水果饮料、碳酸水果饮料、蔬菜和果汁 含胡萝卜、以蔬菜为主的婴儿食品和含肉类的婴儿食品，范围为1.9µg/kg 至18.6微克/千克。然而，在浓度范围内，仪器响应的线性已被证明 从0.5微克/千克到20微克/千克。定量限（LOQ）取决于仪器，但可以 通常预计在0.5µg/kg至1.0µg/kg范围内。交叉引用:ISO 3696:1987EN ISO 3696:1995 ISO/IEC 17025:2005 Ed 1ISO/IEC 5725-2:1994ISO 1042:1998EN ISO 1042（采用ISO 1042:1998）2002/657/E购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN 16857:2017 specifies a method for the determination of benzene in soft drinks, other beverages and vegetable-based infant foods, by headspace gas chromatography mass spectrometry (HSGC- MS). The method has been validated in an interlaboratory study via the analysis of spiked samples of carbonated soft drink, still fruit-based drink, carbonated fruit-based drink, vegetable and fruit juice containing carrot, infant food vegetable based and infant food containing meat, ranging from 1,9 µg/kg to 18,6 µg/kg. However, linearity of the instrument response was proven for the concentration range from 0,5 µg/kg to 20 µg/kg. The limit of quantification (LOQ) depends on the instrument but can generally be expected to be in the range from 0,5 µg/kg to 1,0 µg/kg.Cross References:ISO 3696:1987EN ISO 3696:1995 ISO/IEC 17025:2005 Ed 1ISO/IEC 5725-2:1994ISO 1042:1998EN ISO 1042 (ISO 1042:1998 Adopted)2002/657/ECAll current amendments available at time of purchase are included with the purchase of this document.
