Pesticides multi-component analysis

Simultaneous analysis was carried out on multi-component pesticide residues in various food products. Results obtained indicated excellent reproducibility (10% at 5 ppb) and linearity with better than 0.995 in the range ofO.l-lOOppb (0.1-100 pg/pL injected). Figure 4.54 shows as example the calibration curve for propazine at 0.1-100 ppb with a corresponding chromatogram at 1 ppb, showing excellent reproducibility R = 0.9998).
