Assessment of the measurement value relative to the ideal range defined by you.
Measurement value for this parameter is outside the value range of this method.
Note(s)
-> The temperature of your water sample should be between 20°C and 25°C.
-> Fluorides and polyphosphates in the sample water will reduce the
measurement results. So long as no fluoride has been actively added this
effect is negligible. Otherwise, the result will be, depending on the fluoride
concentration in the water, 0.01 to 0.23 mg/l too low. To take this effect into
account the fluoride content in the water must be determined in a separate
procedure. Multiply the separately determined fluoride value with 0.4 and
then add 1 to this result, which will render the factor by which the
measurement result (aluminium) must be multiplied to get the correct value.
Example:
Determined fluoride value = 0.6 mg/l; multiplied with 0.4 = 0.24; plus 1 = 1.24
(= factor). Determined aluminium value = 0.15; multiply with the above factor
(1.24) = 0.186 mg/l aluminium concentration.
-> Iron and manganese are eliminated by the reagent tablet and have no
influence on the measurement result.
