The main structure
was made by plastic
injection molding
and two PSA layers
were added on either
side. It included four
reaction chambers
for the multiplex
measurements
Reaction mixture were
pipetted into each
detection chamber and
allowed to dry, leaving
one chamber empty for
quality control. The
LED emitted and
transmitted by the
reagent. The step
motor rotated the
camera through all
four chambers and
were then processed
by the microcontroller.
The color changes
were measured by a
custom analyzer and
built-in optical system
• GLU
• TG
• TC
Multi-index
monitoring was
done with a high
accuracy and low
cost, while
maintaining
excellent
consistency with
conventional
chemistry analyzers
