A device for measuring fluid flow rates over a wide range of flow rates (<1 nL / min to >10 μL / min) and at pressures at least as great as 2,000 psi. The invention is particularly adapted for use in microfluidic systems. The device operates by producing compositional variations in the fluid, or pulses, that are subsequently detected downstream from the point of creation to derive a flow rate. Each pulse, comprising a small fluid volume, whose composition is different from the mean composition of the fluid, can be created by electrochemical means, such as by electrolysis of a solvent, electrolysis of a dissolved species, or electrodialysis of a dissolved ionic species. Measurements of the conductivity of the fluid can be used to detect the arrival time of the pulses, from which the fluid flow rate can be determined. A pair of spaced apart electrodes can be used to produce the electrochemical pulse. In those instances where it is desired to measure a wide range of fluid flow rates a three electrode configuration in which the electrodes are spaced at unequal distances has been found to be desirable.

Measurement of the extinction coefficient k is employed for effective and prompt in-line monitoring and / or controlling of the metal film composition. The dependency of the extinction coefficient on the composition of a metal compound is characterized by measuring the extinction coefficients of a series of the metal compound with different compositions. A monitor metal film is then deposited on a wafer. The extinction coefficient k of the film on the wafer is measured and a film compositional parameter is extracted. The wafer processing may continue if k is in specification or the needed compositional change in the film may be extracted from the measured value of the k and the established dependence of k on the composition of the film for out-of-spec k values.

A method for determining reservoir architecture using modeling of a non-equilibrium distribution of at least one analyte in reservoir fluids.
