应该是这个，但是我都没有找到这个产品的分析方法，不论产品或者残留的。

Abstract：
In this work, the combined use of solid-phase extraction (SPE) and on-line preconcentration strategies as normal stacking mode (NSM) and stacking with matrix removal (SWMR) for the ultrasensitive and simultaneous capillary electrophoresis-ultraviolet analysis (CE-UV) of five triazolopyrimidine sulfonanilide pesticides (i.e., diclosulam, cloransulam-methyl, flumetsulam, metosulam and florasulam) in different types of water is investigated. An adequate separation electrolyte for the separation and stacking of these pesticides was obtained, considering also its compatibility with MS detection, which consisted of 24 mM formic acid and 16 mM ammonium carbonate at pH 6.4. It was observed that the use of this running buffer together with the SWMR preconcentration method provided the best results in terms of sensitivity (between 6.54 and 11.9 μg/L) and peak efficiency (up to 550000 theoretical plates per meter, NTP/m). When this on-line preconcentration procedure was combined with an off-line sample preconcentration step as SPE using C18 cartridges, the selected herbicides could be detected in the ng/L range. The optimized SPE-SWMR-CE-UV method was applied to the determination of the selected group of pesticides in spiked and non-spiked mineral and stagnant waters. Recoveries ranged between 55 and 110% and limits of detection between 131 and 342 ng/L. This work shows the great possibilities of the combined use of SPE-SWMR-CE-UV to overcome the sensitivity problems usually linked to CE analysis.

这个里面不会有分析方法。这个是对dow 的产品在加拿大登记回顾和建议，包括对产品介绍，危害评估等各方面内容，是个产品的总结性文档。我们做国外登记的时候时常会到这种文档上找资料。

原文由 redanqi 发表:问个问题。这种可以同时测很多种农药的分析方法，也适用于测一种农药的吗？

你好！关于多残留分析是否可以用于单个残留分析的问题，个人看法是肯定可以的，首先既然前处理方法能处理多种目标物，那么只对一种目标物也是适用的；其次，仪器条件也是一样的，对多种农药残留目标物适用的话对单个的也是适用的。主要是多残留的分析方法和检测条件可能要复杂一些，如果要对单个目标物进行分析的话，应该对前处理及仪器条件进行一些简化、优化。

你好！上传的时候只看了一下目录，没有看具体的内容，刚才看了一下内容，的确是没有具体的分析方法，不好意思了。

没什么。
我们有时候客户要分析方法，就写个HPLC，啊哈哈
