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.
- GLP compliance:
- not specified

Applicant's summary and conclusion
- Conclusions:
- Henry's Law constants of 20 -106 M/atm were derived between 279 and 265 K.
- Executive summary:
Henry's law constant was obtained from measured uptake kinetics determined via the droplet train technique coupled to a mass spectrometric detection. Henry's Law constants of 20 -106 M/atm were derived between 279 and 265 K.
