ASTM method D8045 beats ASTM D664

Superior thermometric method for complex petroleum samples.

ASTM method D8045

The new method describes thermometric titration and was developed by Metrohm together with industry leaders using the 859 Titrotherm titrator.

Method D8045 demonstrates the superiority of thermometric titration for complex petroleum samples, as it provides for better reproducibility of results, is significantly faster, and consumes less reagent than the commonly used method D664.

Compared with potentiometric titration (ASTM D664), this method is more

  • Robust – Oil matrix does not interfere with the measurement
  • Faster – Analysis in one third of the time of a potentiometric method
  • Simpler – No sensor maintenance


Money saver

Above all, this method will save you money, as you will need less solvent per analysis.
