Abstract
The analysis method for fluroxypyr ester by high performance liquid chromatography (HPLC) is established in this paper. This method is based on the chemical and physical properties of fluroxypyr ester to optimize determination conditions such as the sample solvent, mobile phase and chromatographic column and detection wavelength. The different mass fraction of samples were analyzed by the following conditionds: the mobile phase is methanol-water, and the column is stainless steel filled with packing of Hypersil BDS C18 5 μm, which size is 250 x 4.6 mm (i, d), and the solvent is methanol, and the detector is ultraviolet absorption detector, and the flow velocity is 1.0 mL/min, and the wavelength is 235 nm. The experimental results show that the standard addition recovery is 99.3% ~ 100.3%, the standard deviation is 0.1%, the regression equation is y = 491.78 + 501.31 x, and the linear correlation coefficient is 0.9997.
