Biodegradation Testing

ASTM D5291 :

Instrumental Determination of Carbon, Hydrogen, and Nitrogen in Petroleum Products and Lubricants

It’s the standard that covers the simultaneous analysis of carbon, hydrogen, and nitrogen in these types of samples.

The analysis of these elements is valuable because it helps understand the complex nature of the samples. The results can be used to estimate the potential and yields during processing and refining in the petrochemical industry.

The concentration of nitrogen indicates the presence of additives in the samples. Knowing this can help predict the performance of the products. Some petroleum products naturally contain nitrogen.

Understanding the hydrogen content in the samples is useful for evaluating their performance characteristics. The hydrogen-to-carbon ratio is also important in assessing how well the upgrading processes are performing.
