Abstract:
Reusable network of spatially-multiplexed microfliuidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid. System and method for photometric measurements of multiple fluid samples employing such network of channels.

Claim (Index 1):
A method for performing a photometric measurement, the method comprising:\n temporarily stopping a flow of a first fluid sample, passing through a first cuvette of a first microfluidic channel of a microfluidic chip, for a first duration of time that is sufficient\n to immobilize said first fluid sample, \n to prevent a first displacement of said first sample with respect to the first cuvette, and \n to carry out a first photometric measurement of an analyte in said first fluid sample,\n wherein the microfluidic chip contains multiple substrates integrated with one another along their corresponding surfaces to form a stack of substrates with at least one interface; \n \n performing said first photometric measurement by:\n a) transmitting light from a first light source to a first photodetector through the first cuvette containing said first fluid sample that has been delivered to the first cuvette from a first inlet through a first inlet channel that traverses said at least one interface; and \n b) while said first displacement is prevented, acquiring first data from the first photodetector, said first data representing said analyte in the first fluid sample; \n and completely removing the first fluid sample from the first cuvette through a first outlet channel and a first fluidic valve operably cooperated with the first outlet channel.
