Detection of 18 acrylic compounds in intelligent electronic wearable products by tube adsorption-thermal desorption/cold trap capture-GC-MS

建立了吸附管采样-热脱附/冷阱捕集-气相色谱-质谱法测定智能电子穿戴产品中18种丙烯酸酯类化合物挥发量的检测方法。利用TenaxTA吸附管采集样品,通过热脱附/冷阱捕集,GC-MS进行测定。18种丙烯酸酯类化合物在0.01μg~0.1μg范围内线性良好,相关系数均大于0.995。当采样体积为2L时,方法的检出限为0.2416~1.1134μg/m^(3)。在0.01μg、0.05μg加标水平的回收率为88.1%~119.4%,精密度为0.8%~6.8%。该方法快速、准确,可以满足智能电子穿戴产品中丙烯酸酯类化合物挥发量的快速检测。

18 acrylic ester compounds have good linearity relationship in the range of 0.01μg-0.1μg,and the correlation coefficients are all greater than 0.995.When the sampling volume is 2L,the detection limit of the method is 0.2416-1.1134μg/m^(3).The recoveries range in 88.1%-119.4%while the standard level is 0.01μg and 0.05μg,and the precision is 0.8%-6.8%.This method is rapid and accurate,which can meet the requirements of rapid detection of volatile amount of acrylic compounds in intelligent electronic wearable products.
