Statistical analysis of the results warrants classification as Provisional, despite only 7 sets.
All sets were derived from combustion followed by infrared spectroscopy.
Statistical analysis of the results warrants classification as Provisional, despite only 7 sets; three and four acid digestions only.
Two to four acid digestions.
Digestions by two acids excluded as statistical outliers.
