Total Sulfur in Fatty Acids and Waste Vegetable Oils by TS 7000 Compliant to ASTM D5453
Sulfur content in vegetable oils, animal fats, and waste vegetable oils varied greatly among these samples. Oil seeds can contain sulfur as high as a few thousand ppm.
In many countries the sulfur content standard allows maximum levels to be 10 or 15 ppm in automotive fuels, which includes biodiesel. It is known that when animal fats and waste vegetable oils are used for biodiesel production, the sulfur content is expected to be high, due to the presence of sulfur-containing compounds such as proteins. In addition to this, water-washing of the biodiesel may be a critical step for sulfur removal to obtain a good fuel quality biodiesel which does meet the respective allowable sulfur limit. This application note described the analysis and sulfur content in set of undiluted fatty acids which contains partly waste vegetable oils with low and high ppm sulfur content. With use of the TSHR TS 7000 model equipped with heated autosampler tray to maintain the sample in liquid form, this configuration enables customers to analyze the samples fully automatic in compliance to ASTM D5453 method.
Our Impact
TSHR has been helping labs achieve their elemental analysis goals with dedicated solutions. Our vision is to develop innovative reliable combustion analyzers that enable customers to make their work productive and more easier.
To help labs excel we offer Application Notes across the Combustion Analyzer product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.
Whether your needs center around an ASTM Standard or EN/ISO methods, or a sample matrix-based outcome TSHR has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
