About the Course

This test method covers the determination of hydrocarbon types over the concentration ranges from 5 to 99 volume percent aromatics, 0.3 to 55 volume percent olefins, and 1 to 95 volume percent saturates in petroleum fractions that distill below 315 degrees C. This test method may apply to concentrations outside these ranges, but the precision has not been determined. Samples containing dark-colored components that interfere in reading the chromatographic bands cannot be analyzed.

The course can be completed in about one hour.

Learning Outcomes

By the end of this course, you will be able to:

• Define apparatus and related components, including measurement requirements for adsorption columns

• Recognize sampling requirements, including those for sample temperature

• Identify procedure for preparation of apparatus

• Recall procedure for determination of hydrocarbon types of total aromatics, total olefins, and total saturates in petroleum fractions that distill below 315 °C

• Identify procedure for calculating the hydrocarbon types

• Recall reporting procedures as outlined in ASTM D1319
