Summary

A new capillary inlet system was used with a magnetic sector mass spectrometer to analyse headspace gas from air-sparged aqueous solutions of methanol and ethanol. The system responded to pulse additions within 2 minutes and gave ≥90% of equilibrium response after 10 minutes. No memory effects or hysteresis were observed. Signal to concentration ratio was linear with alcohol concentrations up to 5 g/L. Liquid ethanol concentration in aerobic yeast fermentation was followed successfully by on-line headspace gas analysis.
