Gas chromatography of organophosphorus insecticides

Gas chromatography of organophosphorus insecticides. Bi, Fu-chun; Wu, Guo-xu (Institute of Elemental Organic Chemistry, Nankai University, Tianjin 300071, Peop. Rep. China). Huaxue Gongye Yu Gongcheng (Tianjin, China), 18(3), 156-160 (Chinese) 2001 Huaxue Gongye Yu Gongcheng Bianjibu. CODEN: HGGOER. ISSN: 1004-9533. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Under similar anal. conditions (gas chromatograph, detector, liq. phase and carrier gas), a 0.53mm i.d. capillary column coated with Apiezon L will run a sample three times faster than a 2m long and 5% Apiezon L packed column. The 0.53mm capillary gas chromatog. avoids the thermal degrdn. of some pesticides such as phoxim, Me phoxim, naled and trichlorfon.99675-03-3. Conceptually the 10m ′ 0.53mm ′ 0.70 mm film capillary column is designed to be alternatives to regular 1/8 in. stainless steel or 2mm i.d. glass column, 2m long with liq. phase loadings of 3%~5%.

Determination of organophosphorus pesticides in Lycium barbarum by gas chromatography with flame photometric detection. Li, Li; Liu, Fengmao; Qian, Chuanfan; Jiang, Shuren; Zhou, Zhiqiang; Pan, Canping (College of Science, Department of Applied Chemistry, China Agricultural University, Beijing 100094, Peop. Rep. China). Journal of AOAC International, 90(1), 271-276 (English) 2007 AOAC International. CODEN: JAINEE. ISSN: 1060-3271. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 5 An anal. method was developed to det. 14 organophosphorus pesticide residues in Lycium barbarum, which is both a botanical medicine and a food. A 5 g sample is mixed with 10 mL Et acetate and, after shaking and centrifuging, 5 mL of the upper layer is removed, concd., and analyzed by gas chromatog. (GC) with flame photometric detection. The essential feature of this method is that, for the purpose of reducing the burden of the GC system, 0.01 g activated carbon is used to adsorb pigments during the cleanup procedure. Av. recoveries of 14 organophosphorus pesticides added at 0.05, 0.1, and 0.5 mg/kg were 66.84-102.42, 71.07-97.93, and 62.50-96.24%, resp. Limits of detection ranged from 5 to 15 mg/kg. The identities of the 14 pesticides were confirmed by GC/mass spectrometry detection in the selected-ion monitoring mode. This method is sensitive, simple, rapid, inexpensive, and safe. .
