Fusel Oil & Methanol Analysis

Sample volume (mL) Sample ABV (%) Separated oil volume (mL) Fusel oil density (g/mL)

Calibration slope m (abs./mg/L) Calibration intercept b Measured absorbance A Dilution factor Sample ABV (%)

Calculated result (mg/dm³ absolute alcohol) Your standard's limit (mg/dm³)

Enter your own limit — verify the exact figures for your specific standard separately as needed.

This method is sensitive enough only for high fusel-content (raw) spirit — see the warning in Theory.

Concentration in original sample—

Concentration in absolute alcohol—

Calibration m/b values must be built with your specific instrument/reagents — never use someone else's or an old calibration.
