Standard Test Method for Measuring Visible Spectrum of Asphaltenes in Heavy Fuel Oils and Crude Oils by Spectroscopy in a Microfluidic Platform
 N D7996

Annotation

This test method covers the measurement, either in the laboratory or in the field, of visible spectra of asphaltenes and maltenes in gas oil, diesel fuel, fuel oils, residual fuel oils, lubricating oil, bitumen, and crude oil using microfluidics and spectrographic techniques.2

These measurements can be related quantitatively to the mass percent of asphaltenes present in the sample.

The test method is limited to asphaltene-containing oil with asphaltenes content less than 15 % by mass.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2 This method and the apparatus are covered by US Patent 8,269,961 and Canadian Patent 2,800,879. Interested parties are invited to submit information regarding the identification of an alternative(s) to this patented item to ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
