사양

간섭: Calmagite/EDTA method: Some metal ions interfere by causing fading or indistinct end points or by stoichiometric consumption of EDTA.
HNB method: dissolved Copper Cu(II) > 2 mg/L, Iron Fe(II) > 20 mg/L, Manganese > 10 mg/L, Zinc > 5 mg/L, Lead > 5 mg/L, Aluminium > 5 mg/L and Tin Sn(IV) interfere. Orthophosphate precipitates Calcium at the pH of the test. Strontium and Barium give a positive interference and alkalinity in excess of 300 mg/L may cause an indistinct end point in hard waters.
Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
