Residual s-triazines were isolated from forage and milk samples by methanol/chloroform extraction followed by column purification. The evaporated extracts were dissolved in acetone and analysed by gas chromatography with NPD detection and mass spectrometry. The detection limits for both methods were found to be about 5 approximately 10 ng of each s-triazine. The selective ions of the 10 s-triazines investigated (simazine, atrazine, propazine, terbuthylazine, cyanazine, desmetryne, ametryne, prometryne, terbutryne and methoprotryne) were chosen on the basis of an electron impact mass spectrometry study of the s-triazine standards and the whole mass spectra are given. Special attention was paid to the fragmentation of cyanazine and the general cleavage pathways of the s-triazines under investigation.
通过甲醇/氯仿萃取，随后进行柱净化，从饲料和牛奶样品中分离出残留的均三嗪。将蒸发后的提取物溶解在丙酮中，采用氮磷检测器气相色谱法和质谱法进行分析。发现两种方法的检测限均为每种均三嗪约5至10纳克。根据均三嗪标准品的电子轰击质谱研究，选择了所研究的10种均三嗪（西玛津、莠去津、扑灭津、特丁津、氰草津、去草净、莠灭净、扑草净、特丁净和甲氧丙净）的选择性离子，并给出了全质谱图。特别关注了氰草津的裂解以及所研究均三嗪的一般裂解途径。
