Materials and methods

Test guideline

Qualifier:

no guideline followed

Principles of method if other than guideline:

The uptake coefficients of carbonates on aqueous surfaces were measured as a function of temperature and composition of the liquid phase using the troplet train technique coupled to a mass spectrometric detection. From the kinetic data, Henry's Law constant was derived between 265 and 279K.
