Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
Surface tensions were measured with an automatic surface tension meter model CBVP-A3 (Kyowa, Japan) which works by the Wilhelmy-plate method. The platinum plate was thoroughly cleaned and flame-dried before each measurement. Calibration was performed periodically under atmospheric pressure, in accordance with specifications, using two 200 mg calibration masses. All liquids were thermostatically controlled to within +/- 0.05 K with circulating thermostat water to a jacketed sample vessel. The uncertainty of surface tension measurement was estimated to be within +/- 0.3%.
