In this application note we will successfully validate a method for the analysis of residual solvents by GC-FID. A technical grade active ingredient (eugenol) will also be tested.

Scion Instruments offers the solution for detailed hydrocarbon analysis (DHA). Spark ignition engine fuels consists out of hundreds of hydrocarbon compounds, with this method according to ASTM D6729 these components can be distinguished and analysed. The ASTM D6729 describes a standard test method for individual components in spark ignition engine fuels by high resolution gas chromatography.

The American Standard, ASTM D6584, is the standard test method commonly used for the quantitative determination of free and total glycerin content in Fatty Acid Methyl Esters (FAME), typically intended for pure biodiesel or as a blending component for domestic and diesel fuels. Total glycerol content is calculated from the results obtained. The method is suitable for FAME from rapeseed, sunflower and soybean oils.

Biodiesel is produced by transesterification of the parent oil or fat with an alcohol, usually methanol, in the presence of a catalyst, usually potassium hydroxide or sodium hydroxide, or, increasingly, alkoxides. The resulting product can contain not only the desired alkyl ester product but also unreacted starting material mono-, di- and triacylglycerides, residual alcohol and catalyst...

For biodiesel to be used as a motor fuel or blended with petroleum diesel, it must conform to standard specifications (ASTM D 6751 or EN-14214). There are standard GC methods in use today to determine if biodiesel conforms to the standard specifications, one of which is EN-14103, used to determine the ester and linoleic acid methyl ester content...

ASTM D7423 is a standard test method for determination of oxygenates C2-C5 in hydrocarbon matrices. The SCION low level oxygenates analyzer is designed and optimised to quantify ppm and sub levels of ethers, alcohols, ketones and hydrocarbons in gas, liquid and LPG samples.

There has been a growing demand for the analysis of oils, fats and fat containing food products especially surrounding the edible oils market. The most common analysis of such products are the determination of fatty acid methyl esters (including cis and trans isomers and omegas...

The analysis of methanol in crude oil according to ASTM D7059: “Standard Test Method for Determination of Methanol in Crude Oils by Multidimensional Gas Chromatography.” In the production of crude oil, methanol is often added to prevent formation of hydrates (i.e., solid water-hydrocarbon structures) that block transportation via pipelines. However, methanol, as with most oxygenated components, will poison catalysts when the crude oil is converted into other products...

Aldehydes are important compounds regularly use in the chemical industry. Sick house syndrome is a medical condition caused by poor air quality in enclosed indoor spaces and the presence of specific volatile organic compounds (VOCs) such as formaldehyde. It is vital that the level of formaldehyde and associated compounds are regularly measured and controlled especially in working environments in which formaldehyde is handled. SCION Instruments developed a method for the simultaneous analysis of seven DNPH (2,4- Dinitrophenylhydrazine) derivatised aldehydes plus one derivatised ketone.
