The most widely used method for ionic liquid density measurement is the vibrating-tube densitometer a method which relies on a calibration as a function of temperature and pressure using appropriate reference fluid.For many reported ionic liquids this is not routinely performed and corrections for the case of viscous fluids (i.e., >100 mPas) are often ignored. Despite these factors the densities of ionic liquids measured with vibrating-tube densitometers have a standard uncertainty to within 0.1%. Alternative methods include the calculation of density through speed of sound measurements or piezometric methods. Both approaches are relatively complex technically but present the advantage of providing extra thermodynamic property data.
