1. A portable interferometric system for detection and quantification of analyte within an agricultural test sample composition, the system comprising:
an optical assembly unit, the optical assembly unit comprising a light unit and a detector unit each adapted to fit within a portable housing unit;
a cartridge system adapted to be inserted in the housing unit and removed after one or more uses, the cartridge system comprising:
an interferometric chip including one or more waveguide channels having a sensing layer thereon, the sensing layer adapted to selectively bind or otherwise be selectively disturbed by one or more analytes within the agricultural test sample composition; and
a flow cell wafer; and
a cartridge housing enclosing the interferometric chip and flow cell wafer; and
an alignment means for aligning the cartridge system within a cartridge recess in the optical assembly unit upon insertion thereby providing optical and microfluidic alignment of the interferometric chip and flow cell wafer.
