Note
If the copper concentration exceeds 1.50 ppm
or if the sample is very turbid or dark red
colored, it is recommended to dilute the
sample 10 times with
Mi550S1-0
Wine
Solvent-1 and repeat the complete
measurement procedure starting from the
beginning, taking 15 mL of diluted wine sample
in vial A for zero-sampling and 15 mL in vial
B for reading. In this case the displayed value
needs to be multiplied by 10 to compensate
for dilution.
