“…If a UV detector is used, a mobile phase of 80% cyclohexane, 19% CC14, and 1% acetonitrile can be used to separate the fenvalerate diastereomers; all other instrument conditions are the same as reported for the other studies reported herein. This system with retention times of 11.5 and 12.6 min for the two diastereomers is comparable to that of Mourot et al (1979) in terms of analysis time and resolution but yields constant retention times.…”

“…Fenvalerate is unstable under gas chromatographic conditions (Mourot et al, 1979). Formulation analysis was reported by Mourot et al (1979) and involved direct analysis with high-performance LC-UV using both reversed and normal-phase conditions. It was reported that with reversed phase, aside from interference from the alkylbenzene in the formulation, the diastereomers were not separated; with normal phase retention times could not be kept constant but slowly decreased.…”

The pyrethroid insecticides resmethrin [(5-benzyl-3-furyl)methyl cis,frans-(±)-2,2-dimethyl-3-(2methyl-l-propenyl)cyclopropanecarboxylate], permethrin [3-phenoxybenzyl cts,irons-(±)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate], and fenvalerate [(±)-a-cyano-3-phenoxybenzyl (±)-2-(4-chlorophenyl)-3-methylbutyrate] in formulated material were analyzed by using high-performance liquid chromatography with a silica column (10-yum Partisil) and carbon tetrachloride mobile phase containing 0.85,1, and 2.5% (v/v) acetonitrile, respectively, for the three insecticides. The in-line detectors used were an infrared (IR) detector operated at the carbonyl or the C-0 absorption band of the insecticides and an ultraviolet detector operated at 280 nm. The selectivity of the IR detector was demonstrated in that aromatic solvents in the formulation did not interfere in the analysis. Minimum detectable levels for the IR detector were 1 pg for resmethrin and permethrin and 2 µg for fenvalerate.The pyrethroid insecticides are promising new compounds for chemical insect control. Residue and formulation analytical methods are needed as the available published literature for these compounds is still limited.Three pyrethroids of economic importance are resmethrin, permethrin, and fenvalerate.Resmethrin formulation analysis has been reported (Heath, 1972) by gas chromatography with a flame ionization detector, and the cis/trans ratio was determined from the nuclear magnetic resonance spectrum of chrysanthemic acid formed after hydrolysis of resmethrin. The same analytical system was used (Simonaitis and Call,

“…The number of direct separations of isomers has increased dramatically during the last few years along with a concurrent development of HPLC and the surface-modified silicas commonly used in this technique. 14,15 Okamoto et al have resolved the four isomers of a pyrethroid on a polymer based chiral column. 16 The separation of permethrin and some of its degradation products was studied by HPLC.…”

Fenvalerate residues on cattle hair coat from impregnated ear tags

1989

View full text Add to dashboard Cite

A simple small‐scale method for the determination of fenvalerate residues on cattle hair by gas–liquid chromatography with electron capture detection was developed and applied to the determination of fenvalerate residues from BovaidR ear tags. Recoveries were found to be 96–104% at 10–100 μg g−1 levels of fenvalerate. The minimum detection limit of this method was 1 pg g−1. With one ear tag, fenvalerate was adequately distributed over the entire body and persisted for at least 80 days on the hair of cattle.
