MOBILE DEVICE BASED ON AN ARRAY OF SENSORS FOR THE ANALYSIS OF SMALL VOLUME BIOASSAYS Russian patent published in 2022 - IPC G01N27/12 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology, namely for the express analysis of gas mixtures released by humans and animals. A mobile device based on an array of sensors for analyzing small-volume bioassays includes a three-chamber housing, inside which, in the first non-assembled chamber, connected by thread to the lid on one side, there are electrical circuits connected to n sensors with sorbents of different nature and fixed in the lid in sockets with holders, but located in the second chamber, which is fixed by thread to the lid on the other hand, inside this chamber there is a cone limiting the area of sensors and samples, electrical circuits are connected to an external power source by a USB bus through a socket with a computer, laptop, through which information is also transmitted to the device software, while monitoring the power and operating status of n sensors is carried out by triggering, respectively, n light indicators located on the outside of the first chamber, a third chamber is wound on the second chamber from below, hollow inside, in which there is a pull-out tray for a container with a bioassay that releases easily volatile compounds.

EFFECT: ability to measure and record volatile compounds: biomarkers of normal and pathogenic processes without special preparation of the sample for analysis.
