Abstract Using a new, sensitive photo-ionization detector in a portable gas chromatograph that operates at ambient temperature, a method was developed for determining ethylene dibromide in air as low as 19 ppb. Vapor standards were prepared for calibration of the detector; concentrations in these standards were accurately determined by using a flame ionization detector. This detector was previously calibrated with an aqueous standard of ethylene dibromide. Using the 2 gas chromatographs, the loss of ethylene dibromide through sorption from the atmosphere of the vapor standards was determined. Solubility of ethylene dibromide in water was also established at 3 temperatures, using the flame ionization detector.

Abstract We describe a modified gas-chromatographic method for acetate in serum or plasma, intended for use in the investigation of acetate intolerance in hemodialysis patients. The assay may be adapted for use with a single-column gas chromatograph equipped with a flame ionization detector. The analysis, made isothermally, requires only 0.5 ml of plasma or serum. Only one deproteinizing step is required to prepare the sample for analysis. Additionally, we present preliminary findings of an ongoing acetate-intolerance study.

Abstract A rapid, specific method for methanol in aqueous and nonaqueous liquids has been developed and studied collaboratively. The method involves sample dilution with dioxane to approximately 0.4% methanol and injection into a gas chromatograph fitted with a Porapak R column and a flame ionization detector. A collaborative study, with 7 collaborators each reporting on 6 test portions, showed coefficients of variation of 2.7, 2.1, 2.3, 4.2, 1.8, and 3.5. The method has been adopted as official first action.

Abstract A rapid and simple method of analysis has been developed for sorbitol in cooked sausage products. Sorbitol is extracted from cooked sausage products with water, an aliquot of the extract is freeze-dried, and the trimethylsilyl (TMS) derivative of sorbitol is formed. An aliquot of the TMS-sorbitol is injected into a gas chromatograph and measured by a flame ionization detector. Analysis of fortified samples shows that the recovery compares well with known amounts of sorbitol added.

Many municipalities are turning to landfill biogas to generate electricity. A major challenge is the presence of volatile cyclic organic siloxanes in the biogas stream, which upon combustion form silica deposits, decreasing the lifetime and warranty of reciprocating engines and turbines. With literature reporting that the analysis of biogas for siloxanes is complex, an investigation was completed to identify best practices for measuring siloxane concentrations in the biogas. The result is an easy-to-use collection and analytical technique that used commercially available XAD-2 resin ORBO® tubes to capture siloxanes through sorption. Following desorption, analysis was done on a gas chromatograph equipped with a flame ionization detector. Using the developed technique at the Region of Waterloo landfill, the sampled biogas showed the presence of D4-siloxane at an average concentration of 37.6 ± 1.7 mg/m3, while the D5-siloxane concentration was 21.9 ± 1.2 mg/m3. These measured concentrations were higher than those reported by an accredited lab. Investigation suggests that the use of Tedlar® bags by the outside lab to collect the biogas sample affected the reliability and variability of the latter approach.

Abstract A gas-liquid chromatographic method has been developed for the direct analysis of Sevin (carbaryl, 1-naphthyl N-methylcarbamate) technical grade, Sevin 85, Sevin 80, and Sevin 50 formulations. The method consists of dissolving the sample in chloroform containing Thiodan as an internal standard; an aliquot of the supernate is injected into a gas chromatograph with a flame ionization detector and a column packed with 3% SE-30 on 60-80 mesh Gas- Chrom Q. The method compares favorably in accuracy with older methods, is not subject to interferences, is rapid, and has automation possibilities.
