• The drinking water sample should be acidified immediately after the

sample has been taken by adding 10 µL conc. hydrochloric acid per

10 mL drinking water.

Owing to the large temperature dependence of the measured values (≥ 2%/°C), we

recommend you to use the 6.1418.220 Thermostatable measuring vessel with the

calibration curve method.
