Items required
OCMA-500 (this product)
Measuring cylinders (20 mL) or syringes (20 mL, optional): 2 (for solvent and sample)
Dropper (provided): 1 (for hydrochloric acid)
Clean solvent S-316 (optional)
Hydrochloric acid (refer to "Hydrochloric acid" (page 22))
Sample water
Automatic measurement
Deciding the extraction time
40-second extraction results in a uniform extraction state for normal sample water, however,
the optimum extraction time depends on the properties of the sample water.
If you do not know the optimum extraction time of the sample water to be measured, use
semi-automatic measurement or manual measurement to vary the extraction time prior to
automatic measurement, and compare with extraction outside the product to determine the
optimum extraction time.
