This mechanism pipettes the sample rack fed to the ISE on S. sampling position on Sampling line, and discharges it Into ISE diluent bath. A capacitance type liquid surface is used for detection. The cycle time of this mechanism depends on the number of ISE modules: 1 module for 12 seconds, and 6 seconds for 2 modules (same as for model 7700). The mechanism is covered by an acryl cover to avoid biohazard. "
Sipper / vacuum Mechanisms" The sipper mechanism aspirates mixed solution [sample + diluent (DIL)], internal standard solution (IS) and reference electrode solution (REF), and sends added ion selective electrode to the. The vacuum mechanism drains the mixed solution [sample + diluent (DIL)] and the internal standard solution (IS) from the ISE diluent bath. The nozzles of sipper and vacuum Mechanisms are lowered by solenoids vào trong khi aspiration diluent bath.
During operation, vacuuming three times per sample is Performed (1st: drain of the internal standard solution, 2nd: drain of mixed solution [sample + diluent], 3rd : drain of the internal standard solution to clean discharged diluent bath). The operation of vacuum aspiration mechanism is Performed by the vacuum unit of the first module. The aspiration of sipper operation is Performed by the syringe mechanism for sipper. The cycle time of sipper / vacuum Mechanisms is 12 seconds. "
