MICROFLUIDIC COLLECTOR AND METHOD OF DETERMINING CONCENTRATION OF ANALYTE FROM ABSORPTION MEASUREMENTS WITH TEMPERATURE COMPENSATION Russian patent published in 2024 - IPC B01L3/00 G01N33/00 

FIELD: control and measuring equipment.

SUBSTANCE: present invention relates generally to sampling and analysis in agricultural field and more specifically to a fully automated system for sampling soil and other species, agriculture-related samples and analysis of chemical properties. System includes a multilayer substrate for chemical analysis of a microfluidic collector, configured to obtain a temperature-compensated concentration of analytes or other chemical properties associated with the sample. For this purpose, the system uses a programmable controller, a temperature sensor and an absorption coefficient measuring device. System can be used to analyze various types of agricultural samples, including soil, vegetation, organic fertilizers, milk, etc.

EFFECT: sampling system enables to process and analyze several samples for different analytes or chemical properties simultaneously or partially in parallel; preferably, the system can process soil samples "as they are collected" without preliminary drying and grinding to obtain a sample suspension.
