CONSTITUTION: A microelement measuring system by using a mercury dropping electrode includes a second switch valve(120) for selectively opening a pure water case(100), an electrolyte case(102) and a sample case(104) according to a set position of a second tube(122) to supply liquid via a connection line(124), a second micro syringe(220) for supplying the liquid introduced via the connection line to a first line(L1) connected to the second switch valve by the operation of a second motor(226), a third switch valve(130) located at a first set position for supplying the liquid to a second line(L2), a second set position for alternatively supplying nitrogen gas introduced from a nitrogen case(160) to the second line or a fourth line(L4), or a third set position for opening or closing flow channels, a fourth switch valve(140) for supplying the liquid introduced via the second line to a cell(12) via a third line(L3), a fifth switch valve(150) for supplying a standard sample introduced from a standard sample container(180) to a fifth line(L5), a third micro syringe(230) for inhaling the standard sample introduced from the fifth line to supply to the cell via a sixth line(L6) and the fourth switch valve, and a recovery case(178) for introducing the fluid discharged from the fourth switch valve via an eighth line(L8) and introducing the solution and mercury in the cell via a ninth line(L9).
