Abstract
A target sample to be chemically analyzed is received at a microfluidic device which is part of an analysis card. The microfluidic device includes at least one input layer configured to receive the target sample, at least one intermediary layer, and at least one readout layer configured to present one or more color attributes at one or more readout regions in response to one or more colorimetric reactions to the target sample. An image of the readout layer of the microfluidic device is obtained. A calibration file that corresponds to the analysis card is obtained. The calibration file includes a calibrated model of at least one color attribute based on data from at least one known chemical attribute of at least one standard sample processed by a calibration card. A data processing function is executed on the obtained image by comparing the one or more color attributes at the one or more readout regions to the calibrated model of the at least one color attribute to determine at least one chemical attribute of the target sample.
