thiofanoxsulfoxide, thiophanatmethyl, triasulfuron, tribenuronmethyl, triflusulfuronmethyl and vamidothion (Figure 2). Liquid chromatography was carried out using a system equipped with a binary pump, degasser and autosampler. For the separation an analytical column Aqua 5 125 A C18 (Phenomenex, Aschaffenburg, Germany) with the dimensions 50 mm x 2 mm was used. The mobile phase A consisted of 80% water and 20% methanol, mobile phase B of 90% methanol and 10% water. Both phases A and B contained 5 mmoL/L ammonium formiate. The flow rate was 0.2mL/min. The mobile phase composition was changed during a run as follows: Starting with 0%, the percentage of B was increased linearly to 100% over 11 min and then kept constant for another 12 min.
