A method is described for the determination of residues of those substituted urea and carbamate herbicides which hydrolyze to give an aromatic amine. The 2,4clinitrophenyl derivatives of the amines, .which are amenable to gas chromatography and possess strong electron-captaring properties, are prepa

An improved gas chromatographic method is described for the determination of all@-and alkoxy-substituted phenols as their 2,4-dinitiophenyl ethers. The gas chromatograpbic analysis is performed on QV-210 glass capillary or SP-2100 fused silica capillary c41Iumns using electron-capture detection. The
