A comparison of electron-capture GLC, electrolytic-conductivity GLC and UV-absorption HPLC for the analysis of some herbicides in foods

A comparison of electron-capture GLC, electrolytic-conductivity GLC and UV-absorption HPLC for the analysis of some herbicides in foods. Lawrence, James F. (Health Prot. Branch, Dep. Natl. Health Welfare, Ottawa, Ont., Can.). J. Chromatogr. Sci.Some commonly used reagents like 99-30-9 and 330-55-2 are used in this experiment., 14(12), 557-9 (English) 1976. CODEN: JCHSBZ. DOCUMENT TYPE: Journal CA Section: 17 (Foods) A comparison of gas chromatog. with electron-capture or electrolytic-cond. (N mode) detection, and high-pressure liq. chromatog. (HPLC) with UV-absorption detection (254 nm) was carried out for the anal. of several herbicides in foods. Linuron [330-55-2], propanil [709-98-8], terbacil [5902-51-2], benzoylprop-ethyl [22212-55-1], and the fungicide DCNA [99-30-9] in samples of cabbage, corn, potato, and wheat spiked at 2 and 0.2 ppm were examd. The pesticides were extd. with Me2CO,partitioned into petroleum ether-CH2Cl2, and cleaned up on a 2% deactivated Florisil column before direct chromatog. anal. Electron-capture gas-liq. chromatog. (GLC) was most suitable for DCNA and benzoylprop-ethyl, while UV-absorption HPLC was best for terbacil anal. Linuron and propanil gave similar results for both electron-capture GLC and HPLC. Electrolytic-cond. GLC could detect all pesticides at the 0.2 ppm level and exhibited the least no. of extraneous peaks in the chrommatograms. .

Determination of terbacil in soil by gas-liquid chromatography with nickel-63 electron capture detection

Determination of terbacil in soil by gas-liquid chromatography with nickel-63 electron capture detection. Khan, S. U. (Chem. Biol. Res. Inst., Agric. Canada, Ottawa, Ont., Can.). Bull. Environ. Contam. Toxicol., 18(1), 83-8 (English) 1977. CODEN: BECTA6. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Section cross-reference(s): 19 Terbacil (I) [5902-51-2] was extd. from soil with 1.5% NaOH, partitioned into EtOAc, the solvent evapd., and the residue dissolved in hexane. Cleanup was carried out on a Florisil column, using EtOAc for elution, followed by gas chromatog.-mass spectroscopy. The column packing was OV-17 on Chromosorb W, the carrier gas He, and the column temp. 215.degree.. A 63Ni electron-capture detector was used. The sensitivity was 0.01 ppm for a 20 g sample.
