摘要
采用气相色谱法测定建筑涂料中挥发性有机物的含量,进行了大量的实验与研究。测定结果表明,水分测定相对偏差为0.03%~0.05%,挥发性有机物相对偏差0.3%~0.5%,加标回收率98%~102%。该方法准确可行,适用于各种建筑涂料样品的生产和监控。
Analytical technique of gas chromatography in determining VOCs of wall coatings has been test-ed and researched.The results showed that the relative standard deviation of water content and VOC were 0.03%-0.05%and 0.3%-0.5%,respectively,recovery was 98%~102%.The method was simple,accurate,time saving and fast.It can be used to produce and supervise various wall coatings.
