High temperature gas chromatography: The development of new aluminum clad flexible fused silica glass capillary columns coated with thermostable nonpolar phases: Part 2

Samples, representative of certain classes of “high molecular weight” and/or less volatile substances, were analyzed by gas chromatography utilizing a new generation of aluminum clad flexible fused silica glass capillary columns containing thin films of a methyl polysioxane stationary phase capable of being operated isothermally to 400–425°C and temperature programmed to 425–440°C. The results obtained here were compared with those described in the literature discussing the latest advances in Supercritical Fluid Chromatography (SFC) in the analysis of precisely the same types of samples. In all instances, the gas chromatographic method provided superior speed of analysis, superior column efficiency, and superior resolution of the component bands. This was due to fundamental factors, favoring the diffusivity of the solutes in both the gas and liquid phases in this process at these high temperatures. Under these circumstances, it is thought that the strength of SFC mainly lies in the analysis of thermally labile samples until the advocates of this technique make more definitive strides in the handling of still higher molecular weight substances well beyond the newly expanded range of gas chromatography.

Analytical methods for anti-doping control in sport: anabolic steroids with 4,9,11-triene structure in urine

Doping control in sport is mandatory to detect and to control the use of prohibited substances. Due to the growing number of targets, the analysis of doping compounds and their metabolites is carried out using established screening methods. However, detection of anabolic steroids with 4,9,11-triene structure in urine is problematic, so it is necessary to improve the methods.We review the state of the art in doping-control analysis of 4,9,11-trien-3-one steroids, providing an overview of the screening and confirmatory methods developed for these analytes in human urine. First, we review chromatographic techniques. We discuss difficulties in the derivatization of those compounds prior to gas chromatography analyses. In recent years, liquid chromatography has been the preferred technique in drug testing in sport, due to the reduced sample pre-treatment, improved limits of detection and comprehensiveness. We also report on advances and limitations of immunochemical techniques for the analysis of this group of substances.     

Quick gas chromatographic method for determining common pesticides in musts and wines

Summary A rapid method based on gas chromatography which determines parathion-methyl, fenitrothion, chlorpyrifos, dichlofluanid, vinclozolin, chlozolinate, procymidone and iprodione is described. It involves quantitative extraction with n-hexane and determination by capillary gas chromatography using an electron capture detector. Pesticides were satisfactorily separated in 15 min with a phenylmethylsilicone fused-silica capillary column under isothermal conditions. Quantitation was carried out using dieldrin as internal standard. The method seems appropriate for oenological laboratory work because of its simplicity and rapidity. It was successfully used to identify and quantify pesticides studied in musts and wines.
