摘要： A method for determining specific heat capacity of fluids includes: (a) injecting a reference fluid into at least one channel of a reference substrate and a sample fluid into at least one channel of a sample substrate; (b) establishing a temperature gradient along the at least one channel of each substrate; (c) measuring temperature differential between the reference and sample substrates along the temperature gradient for a stagnant condition to define a baseline temperature differential, and for each of a plurality of flowrate ratios of the reference and sample fluids flowing through respective channels; and (d) based on the measuring in (c), determining a thermally-balanced flowrate ratio at which the temperature differential corresponds to the baseline temperature differential, and evaluating the specific heat capacity of the sample fluid based on the thermally-balanced flowrate ratio.
