- Under the optimal conditions, the method provided high enrichment factors ranging from 364 to 434, good linearities ranging from 5 to 200 ng g- 1 for metolcarb, baygon and methiocarb and 10 to 200 ng g-1
- For carbofuran and isoprocarb, low limits of detection ranging from 0.58 to 2.06 ng g-1, and satisfactory spiked recoveries (between 90.34% and 101.98% with the relative standard deviation values from 1.21% to
- 5.93%).
