GC-MS法测定水溶性树脂漆中的甲醛含量

Determination of formaldehyde in water resin paint by GC-MS

本文建立水溶性树脂漆中甲醛含量的衍生气相色谱-质谱联用技术测量方法。方法的检出限小于5μg/L,回收率为90%-110%,相对标准偏差小于5%。

GC-MS with derivation was described for the determination of formaldehyde in water resin paint. The detection limit was 5gg/L. The recoveris were 90%-110%.The relative standard deviations（RSDs） of contents of formaldehyde was below 5%.
