Residual Solvent Analysis of Chemical Products by GC-FID with Hydrogen as a Carrier Gas

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.


ASTM D6729, Determination of Individual components in spark ignition engine fuels by 100 metre capillary high resolution gas chromatography

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.


ASTM D6730, Determination of Individual Components in Spark Ignition Engine Fuels

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 D6730 these components can be distinguished and analysed.


Cannabis Potency Analysis by GC FID with Nitrogen Carrier Gas

In this application note we examine the potency levels in Cannabis using a Scion Instruments 436-GC with FID. Hemp and marijuana are becoming more popular because of legalization in multiple countries. The increase of this market also increases the offer of products that contain very different levels of cannabinoids than the content described on the label. Therefore, as quality control it is important to monitor the level of cannabinoids.


Analysis of Free and Total Glycerin in B-100 Biodiesel Methyl Esters (ASTM D6584)

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.


Determination of Free Glycerol Content in Fatty Acid Methyl Esters (FAME) and Biodiesel According to EN-14106

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...


Determination of Total FAME and Linolenic Acid Methyl Esters in Biodiesel

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 - Analysis of Low Level Oxygenates (LOWOX) in Liquified Petroleum Gas (LPG)

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.


Determination of Fatty Acid Methyl Esters in Edible Argan Oil

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...


ASTM D7059 Methanol in Crude Oil Analysis According

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...
