ABSTRACT:
A relaxation time constant associated with a fluid can be determined and then compared with a stored reference value. The difference between the relaxation time constant and the stored reference value can then be calculated in order to provide qualitative and/or quantitative data indicative of an adulteration of the fluid. The relaxation time constant associated with the fluid can be determined by first generating a static charge and then injecting the static charge into the fluid. The charge can then be collected from the fluid and utilized to determine the relaxation time constant.
