Retention Indexes

Abstract A simple method and a series of compounds for a retention indexing study on a linear programmed capillary gas chromatograph are described. References are chlorobenzenes and decachlorobiphenyl, which show the same behavior in this system as Kovat's references (n-alkanes). This retention index system and gas chromatograph with cryogenic coolant apparatus and electron capture detection, is suitable for measuring the retention index of various compounds with characteristic detection ranging from low volatility to high molecular weight.

Ethylene Dibromide

Abstract Ethylene dibromide (EDB) levels in food samples were determined by gas chromatography with a high-resolution capillary column and electron capture detector. The capillary column used was 3 mm id × 25 m cross-linked 5% phenylmethyl silicone. Column temperature was set at 40°C by a coolant containing carbon dioxide gas. Optimum temperatures of the injection port and detector were 200 and 350°C, respectively. The detection limit was 0.5 ppb and linear from 1 to 20 pg on the dynamic range. EDB residues in food samples were extracted with n-hexane by steam distillation. A few impurity peaks appeared near EDB on the chromatogram; however, the EDB peak was resolved. Recoveries of EDB from wheat and brown rice ranged from 66.1 to 99.6%. EDB was detected in 3 samples of imported wheat at a range of 0.74-1.70 ppb, and was not detected at all in 37 samples. The EDB remaining in EDB-fortified cookies after baking was examined. The amounts of EDB were reduced to 30 to 50% of the original amounts by kneading the dough, and to below 1.5% by baking.
