Mobile chemical analysis

A system comprising:

• one or more processing devices, wherein each processing device comprises a memory and a processor operatively coupled to the memory, and wherein the one or more processing devices are configured to:
• obtain an image of a readout layer of a microfluidic device, wherein the microfluidic device is part of an analysis card and comprises at least one input layer configured to receive a target sample to be chemically analyzed, 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;
• obtain a calibration file that corresponds to the analysis card, wherein the calibration file comprises at least one calibrated model of one or more color attributes based on data from at least one known chemical attribute of at least one standard sample processed by a calibration card;
• and
• execute at least one data processing function on the obtained image, wherein the data processing function comprises comparing the one or more color attributes at the one or more readout regions in the obtained image of the readout layer to the calibrated model of one or more color attributes of the obtained calibration file to determine at least one chemical attribute of the target sample.

An apparatus comprising:

• a microfluidic device comprising:
• at least one input layer configured to receive a target sample to be chemically analyzed;
• 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;
• and
• one or more analysis layers operatively disposed between the input layer and the readout layer, and configured to provide one or more colorimetric analysis on the target sample received at the input layer such that the one or more color attributes are presented at the readout layer in response to the colorimetric reactions;
• a code configured to uniquely identify a calibration file for retrieval, wherein the calibration file corresponds to one or more capabilities of the microfluidic device and comprises at least one calibrated model of one or more color attributes based on data from at least one known chemical attribute of at least one standard sample processed by a calibration card, to enable execution of at least one data processing function that comprises comparing the one or more color attributes at the one or more readout regions of the readout layer to the calibrated model of the one or more color attributes of the obtained calibration file to determine at least one chemical attribute of the target sample.
