D5442 - Wax analysis by Boiling Point Distribution
Test Methods
ASTM D5442
To check the carbon number distribution of petroleum derived waxes, AC Analytical Controls developed the AC Wax ASTM D 5442 application. In one analysis the Wax application determines:
- carbon number distribution from n-C17 through n-C44 using internal standardization
- content of normal and unknown carbon matter (UCM) for each carbon number
- C45+ material
- Data on the carbon number distribution and the content of normal and unknown carbon matter is essential to evaluate petroleum wax quality.
Applications
Wax
Features & Benefits
- A table of the wax content, total n-paraffins, total UCM, total C45+ including S, E n-paraffin peak times
- A chromatogram with merged baseline, carbon numbers or boiling point axis, initial final boiling points, start end elution points, net corrected sample area
- A graph of the boiling point distribution plotted in the chromatogram
- A list of calculation parameters
- A report of peak skew and column resolution parameters of the boiling point calibration
- A table and graph with boiling point versus retention time for calibration samples
- A table and graph with boiling point versus mass % for samples
- Report output in CSV that can automatically be transferred to LIMS through a special radio button
