PURPOSE:To facilitate a trace quantity determination dispensing for a sample and dilution liquid and to make accurate the test result, by carrying out the trace quantity dispensing for washing a liquid serving both as the dilution liquid by one determination microsyringe. CONSTITUTION:Quantitative determination for a sample and snatching determination for a washing liquid diluting the sample at the time of washing a nozzle 1, is carried out by a microsyringe 2 by using a dispensing device provided with the microsyringe 2 connected to the sample nozzle 1 being capable of moving up and down and a washing pump 3 connected to the nozzle 1 through the syringe 2 and sending the washing liquid in a washing liquid storage bottle 5 to the nozzle 1. Accordingly, a trace quantity dispensing for the washing liquid serving both as the dilution liquid is carried out by one determination microsyringe 2. |
