Traditional methods such as rotational viscometer and other viscometer methods are limited in their ability to investigate rheological properties of high viscous liquids. This study introduces a new approach to overcome these obstacles. Deep eutectic solvents suffer from high viscosity and they are relatively expensive. Therefore, there is a requirement to both reduce the volumes of samples required and increase the accuracy of the technique at high viscosities. Quartz crystal microbalance techniques have been applied because they provide quick recording, the potential for collecting a large amount of data in a short time. Furthermore, the quartz crystal microbalance microviscometer has the advantage over most other methods of viscometry not in its precision of absolute viscosity measurement but in the very small amount of sample liquid needed for investigation. To test the precision of quartz crystal microbalance a comparison must be made between readings obtained with a rotational viscometer set up alongside. In this investigation a series of deep eutectic solvents with various viscosities and physical characteristics have been tested. The influence of the addition of water to the liquids was also assessed.
