AI Technical Summary
Technical Problem
Existing colorimetric test devices face inaccuracies due to variations in liquid immersion times for different colorimetric reagent strips when performing multiple tests in parallel, caused by differences in flow path lengths.
Method used
A sensor unit with synchronized inflow paths and synchronized inflow timing for test solutions into multiple test areas, using a common flow path and connecting passages to ensure uniform immersion times for each reagent strip.
Benefits of technology
Enables accurate and rapid detection of multiple components in a test solution by synchronizing the inflow of the test solution, minimizing variations in immersion time and enhancing test accuracy.
