This book was released on 1972 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid identification and quantitation of blood ethanol by gas chromatography (GC) has been especially useful to the clinical and forensic chemist, particularly as court evidence in prosecuting drunken drivers. Certain identification can be made and concentration determined rapidly by GC. A number of GC methods are available for ethanol determination in biological liquid samples. Currently, advances are being made in the area of vapor phase analysis [1-4]. Direct vapor injections overcome several disadvantages of liquid sample injection. Liquid samples containing sodium fluoride as a preservative tend to etch the syringe. Clotted samples are no longer a problem with vapor injections and frequent cleaning of the syringe is not required. With direct injection of blood or diluted blood samples, special inlets are necessary and must be changed periodically to remove protein and other nonvolatile deposits. In addition, the life of the columns is increased with vapor samples. According to Henry's law, at a given temperature there is a definite ratio between the concentration of ethanol in the blood phase and the air in direct equilibrium with it. Investigators have verified Henry's law [5-10] for both aqueous and blood ethanol solutions. The method described here consists of equilibrating blood with n-propanol as internal standard and injecting the vapors. Because of the internal standard, the volume of the injected sample is no longer a critical quantity.

Book Synopsis Gas Chromatographic Method for the Determination of Trace Quantities of Diethyl Malonate in Ethanol by : Juan D. Lopez
Download or read book Gas Chromatographic Method for the Determination of Trace Quantities of Diethyl Malonate in Ethanol written by Juan D. Lopez and published by . This book was released on 1988 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents and experimental study conducted to determine a method for analytically detecting and determining trace quantities of diethyl malonate (DEM) in ethyl alcohol using a gas chromatograph equipped with a flame ionization detector. The method developed proved to be effective for determining trace quantities at a concentration (mean) range of 21-840 ng. A linear fit was obtained at this range with an average slope of 1.4032 + or - 0.0063 x 10 to the -7th micro g/au and an intercept of 0.0359 + or - 0.0359 micro g. The correlation coefficient was 0.9996 + or - 0.0009. Based on replicate injections, the accuracy of this method was within + or - 2.4%. Keywords: Chemical analysis, Gas chromatographic method, Diethyl malonate, Ethanol, Ethyl alcohol. (MJM).
