当有机化合物在含有氯的环境下燃烧时,会产生二噁英和呋喃,例如聚氯乙烯(PVC)生产、纸张漂白过程,以及火山爆发等自然原因.二噁英是剧毒物质,并且具有亲脂性,很容易在多种动物体内积累.它们还是潜在的诱变剂和致癌物质.2,3,7,8-四氯二苯并二噁英(TCDD)结构如下:Xevo TQ-S和大气压气相色谱(APGC)组成了一个非常灵敏的检测系统,可以准确测定出限制浓度的二噁英和呋喃.在分析未知浓度的样品时,可能会检测到浓度非常高的化合物.因此,目标化合物的存在会对下一次进样造成样品残留,进而导致定量结果有误.
Dioxins and furans, such as polyvinyl chloride (PVC) production, paper bleaching processes, and natural causes of volcanic eruptions can occur when organic compounds are burned in environments that contain chlorine. Dioxins are highly toxic and have pro-toxic They are also potential mutagens and carcinogens.2,3,7,8-Tetrachlorodibenzodioxin (TCDD) The structure is as follows: Xevo TQ-S and atmospheric pressure Gas Chromatography (APGC) constitutes a very sensitive detection system that accurately measures dioxins and furans at their limiting concentrations. Very high concentrations of compounds may be detected when analyzing samples of unknown concentration. Thus, the presence of the target compound Will cause sample residue for the next injection, which in turn will result in incorrect quantitation.
