AI Technical Summary
Existing colloidal gold immunochromatographic analyzers require at least two devices for on-site quantitative detection, which takes up a lot of space and is complicated to operate, and cannot simultaneously identify colloidal gold test strips and fluorescent test strips.
A multifunctional immunochromatographic analyzer was designed, equipped with a dual-scanning-head structure, including a first scanning head and a second scanning head, which are used to identify colloidal gold test strips and fluorescent test strips, respectively. The test strips are positioned and identified by a cartridge tray shifting unit. The analyzer integrates a detection photoelectric switch and a signal acquisition board, resulting in a compact structure.
It enables simultaneous identification of colloidal gold test strips and fluorescent test strips on a single device, reducing equipment space requirements, simplifying the operation process, and improving detection efficiency and consistency.
