Abstract
An improved system, device and method for characterizing a fluid sample that includes injecting a fluid sample into a mobile phase of a flow characterization system, and detecting a property of the fluid sample or of a component thereof with a flow detector comprising a mechanical resonator, preferably one that is operated at a frequency less than about 1 MHz, such as a tuning fork resonator.
