| Abstract/Summary |
A surface ionization gas chromatographic detector, based upon positive surface ionization, was used in capillary gas chromatography to sensitively and selectively detect nitro pesticides: pendimethalin, trifluralin, flumetralin. Higher sensitivity (better detection limit), substance specificity, and advantageous applicability are reported. Sensitivity to pendimethalin, trifluralin, and flumetralin was 1.4 C g−1, 1.1 C g−1, and 1.0 C g−1, respectively, with the linear range of operation greater than 1 × 105 for these compounds. The minimum detectable level was in the range of 10−13 g s−1. Compared with an atomic emission detector, SID provided a 110 times better detection limit for trifluralin.
