Abstract:
A solution feeding device for feeding a sample solution formed by precisely conditioning the
mixed amount of a standard solution. The solution feeding device comprises a
mixing means (100) having a first flow passage (101), a second flow passage (102), and
a third flow passage (103) allowing these two flow passages to communicate with
each other at their intermediate parts with a flow passage resistance larger than
the flow passage resistance of these two passages, a first storage means (10)
communicating with one end of the first flow passage and storing the sample solution,
a suction means (20) communicating with the other end of the first flow passage
and sucking the sample solution, a second storage means (30) communicating with
one end of the second flow passage through an opening/closing valve (31) and storing
the standard solution, and a syringe pump (40) communicating with the other end
of the second flow passage and sucking and discharging the standard solution
in the opened state and the closed state of the opening/closing valve.
