Method development and validation for boscalid in blueberries by solid-phase microextraction gas chromatography, and their degradation kinetics
Analytical method for the residues of boscalid in blueberries was developed. Fungicide residues were determined by solid-phase microextraction (SPME) coupled to gas chromatography with micro-electron capture (μ-ECD) detector. The effect of pH values and fiber coatings were studied. The SPME fiber co...
