Breakthrough experiments for the C&lt;sub&gt;18&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;SPE cartridge show that the two triazine metabolites are not fully retained and that increasing flow-rate decreases their retention. Standard curve&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;r&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;values of 0.998–1.000 for each compound were consistently obtained and a quantitation level of 0.05 μg/l was achieved for each compound tested. More than 10 000 surface and ground water samples have been analyzed by this method.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
