Method: Ion Selective Electrode (ISE) direct method.

Test Project: K, Na, Cl, Ca, PH, nCa, TCa (up to 7 parameters). Sample: Whole blood, plasma, and serum; Sample size: 100 microliter. Speed: Measurement time under 1 minute (including suction, rinsing, printing). Calibration: One-point/two-point automatic calibration; Automatic tracking of electrode status eliminates drift.
