Abstract
A solution feeding device for feeding a sample solution which is precisely adjusted in the mixed quantity of a standard solution is realized. The solution feeding device comprises: a mixing module () including a first passage (), a second passage (), and a third passage () for providing communications of the midways of those two passages with a higher passage resistance than those of the two passages; a first storage unit () communicating with one end side of the first passage for storing a sample solution; a suctioning nebulizer () communicating with the other end side of the first passage for sucking the sample solution; a second storage unit () communicating through an on-off valve () with one end side of the second passage for storing a standard solution; and a syringe pump () communicating with the other end side of the second passage for sucking and discharging the standard solution, respectively, in the open state and the closed state of the on-off valve.
