- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.
Analyst 113, 1747-1748 (1988). Description of two specific spray reagents for the detection of carbamate insecticide carbaryl: a) 1% (m/v) copper (II)chloride followed by 0. 1% ammonium metavanadate and b) 0. 5% (m/v) potassium hexacyanoferrate (III) in 0. 5% (m/v) potassium hexacyanoferrate (III) in 0. 5% (m/v) sodium hydroxide. Recovery: 100%. Reagent a) has higher sensitivity for degradation products of carbaryl, 1-naphthol, whereas b) has the same sensitivity for both carbaryl and 1-naphthol, ca. 1ng.
J. Liqu. Chromatogr. 23, 3043-3058 (2000). HPTLC of iprodione(3-(3,5-dichlorophenyl)-N-isopropyl-2,4-dioxoimidazolidine-1-carboxamide), vinclozolin (RS)-3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-1,3-oxazolidine-2,4-dione) and cymoxanil (1-(2-cyano-2-methoxyiminoacetyl)-3-ethylurea) on silica gel with hexane - acetone 7: 3, 4:1, 3:2, cyclohexane - ethyl acetate - acetic acid 90:10:1, 8:2:1 and ethyl acetate - cyclohexane 9:1. Quantitation by densitometry at 210 resp. 268 nm. Detection limits for iprodione, vinclozolin and cymoxanil, respectively, 0.2 ppm, 0.43 ppm and 0.5 ppm. Multi-residue, simple and rapid method for simultaneous determination of fungicides.
J. Chromatogr. 292, 117-127 (1984). HPTLC of phenylurea herbicide hydrolysates and their aniline metabolites on silica with dichloromethane or dichloromethane - methanol 99:1 and on RP-18 with acetonitrile -3 % aq. sodium chloride solution 85:15. Prior to development, the applied spots were overspotted with 4 mL of 0.25 DNS chloride solution. An increased fluorescence intensity was obtained by dipping the plates into paraffin - hexane 2:1. Scanning by fluorescence, excitation at 360 nm. Detection limit 1 ng.
J. Planar Chromatogr. 2, 304-309 (1989). HPTLC of 8 PCAs (MCPA, 2,4-D, 2,4,5-T, MCPB, mecoprop, dichlorprop, fenoprop, 2,3-DB) on silica (prewashed) with methanol - dichloromethane 1:1 (first run) and cyclohexane - toluene - acetic acid 20:4:4 (2nd run). Scanning by absorbance at 210 or 278 nm; detection limit 80 ng/zone. Fluorimetric determination after in situ derivatization with monodansylcadaverin; detection limit 10 ng/zone.
J. Liquid Chromatogr. 18, 873-885 (1995). HPTLC on RP-18 silica with methanol - water 85:15 and 70:30. Quantification by densitometry at 200 nm for alachlor and at 220 nm for atrazine.
J. Planar Chromatogr. 15, 11-18 (2002). TLC of chlortoluron, diuron, fluometuron, isoproturon, linuron, methabenzthiazuron, and neburon on diol-modified silica gel with water - acetone - methanol 6:1:3, on amino-modified silica gel with chloroform - toluene 4:1, and on silica gel with benzene - triethylamine - acetone 15:3:2. Detection by fluorescence quenching at 245 nm. Quantitation by densitometry in reflectance mode at 245 nm (or 265 nm for methabenzthiazuron). Two derivatization procedures with fluorescamine were tested on silica gel plates: two variations of pre-chromatographic and three variations of post-chromatographic derivatization. The derivatization after thermal hydrolysis improved the limit of detection 25-fold compared with conventional densitometric analysis. New rapid, inexpensive and sensitive method.
J. Liq. Chromatogr. & Relat. Technol. 29, 2437-2449 (2006). TLC of thifensulfuron methyl, triasulfuron, chlorsulfuron, rimsulfuron, amidosulfuron, and tribenuron methyl on silica gel with benzene - methanol 9:1 in a chamber saturated for 30 min, and on RP phase with acetonitrile - methanol - 0.1% phosphoric acid 7:7:6. Detection by iodine vapor or by spraying with a solution of potassium dichromate (5 g) in sulfuric acid (40 %; 100 g), followed by heating to 150 °C.
Exposure to pyridine for 20 min, followed by irradiation (6 min) by long-wave UV light. Quantification by fluorodensitometry at 420 nm excitation and 550 nm emission. Detection limit 1 ng. Calibration curve was found linear from 2.5-30 ng. Recoveries 87.1-88.7 %.
