产品介绍
Phthalic acid ester compounds (PAEs, also known as phthalate) is mainly used as plastics modified additives (plasticizer), also used for pesticide production, coating, printing and dyeing, cosmetics and spices. With the development of industrial production and the use of plastic products, the most common type of PAEs has become a global pollutant, widely exists in the atmosphere, water, soil, organisms, toxicity in addition to the known teratogenic, cause.
xiang ying analysis technology co., LTD has established the liquid-liquid extraction - XingyingGC7990plus gas chromatography determination of phthalic acid ester compounds in environmental water samples. This method can effectively separate eight kinds of phthalic acid ester compounds, the linear regression correlation coefficient of standard curve were greater than 0.999 9, the minimum detectable amount can reach 10-11 g, relative standard deviation is 0.47% ~ 0.47%, standard addition recovery is 73.5% ~ 73.5%.
邻苯二甲酸酯类化合物(PAEs,又称酞酸酯)主要用作塑料制品的改性添加剂(增塑剂),同时也用于农药、涂料、印染、化妆品和香料生产。随着工业生产的发展及塑料制品的大量使用,PAEs已成为全球性最普遍的一类污染物,广泛存在于大气、水体、土壤、生物体中,其毒性除已知的致畸、致。
滕州市翔鹰分析技术有限公司建立了液液萃取—XingyingGC7990plus气相色谱法测定环境水样中邻苯二甲酸酯类化合物的方法。该方法能有效分离8种邻苯二甲酸酯类化合物,标准曲线线性回归相关系数均大于0.999 9,最小检测量可达10-11g,相对标准偏差为0.47%~1.83%,加标回收率为73.5%~114.6%。
