abstract:
Reversed phase capillary electrochromatography was applied to the determination of phenylurea
herbicides residues in different samples of vegetables and vegetable processed food.
The use of 40% acetonitrile mobile phase content provided a large elution window and strongly
reduced the presence of matrix interferences in real samples. The compounds were baseline
resolved within 14 min with 97612-113312 N/m range by using the short end injection
method. The method was repeatable and linear and applied to the analysis of spiked soya milk
and canned soya shoots samples extracted after a reduced sample pretreatment procedure. The
analysis of vegetables showed some difficulties arising from the complexity and the strong
variability of the matrix.
