Assessment of Total Sulfur in Base Oils - ASTM D7183
ASTM Method D7183 describes the determination of sulfur in aromatic hydrocarbons and other related chemicals. The concentration range for this method is 0.5 to 10 mg/kg and samples can be either directly injected or placed in a boat for combustion and analysis. Base oils are a common type of sample tested using ASTM Method D7183 as the most commonly used base oils have less than 0.03% sulfur.
EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.
To help labs excel we offer Application Notes across our entire 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 a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST 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.
