Novel Methodology for Measuring Temperature-Dependent Henry's Constants of Flavor Molecules.

Shane Avison et al.

Journal of agricultural and food chemistry, 63(28), 6313-6318 (2015-06-23)

A new methodology is presented to measure water-air partition coefficients (Henry's constants) of volatiles, using APCI-MS. Significant advantages over other Henry's constant determination methods include the short measurement and sample preparation time and the possibility for simultaneous measurement of multiple
