Standard colors were determined from standard solutions. However, coexisting substances will

cause inaccurate results. The list below reports substances concentrations under which ones

interferences are insignificant:

≤ 1000 mg/L : As3+, B3+, Ba2+, Ca2+, Cd2+, Cl－, F－, Fe2+, K+, Mg2+, Mn2+, Mo6+, Na+, NH4+, Ni2+,NO3-,,PO43－, SO42－, Zn2+, Phenol, Anionic surfactant

≤ 300 mg/L : Co2+

≤ 200 mg/L : Fe3+

≤ 100 mg/L : Ag+, Cr3+, V5+

≤ 30 mg/L :NO2－, Pb2+

≤ 10 mg/L : Cr6+

≤ 5 mg/L : Au3+, Cu2+

≤ 1 mg/L : CN－, Pt4+

Sub-ppm level : Residual Chlorine, Hydrogen Peroxide

The Palladium PACKTEST is suitable for sea water samples.

Hydrogen peroxide, residual chlorine or other oxidizing chemicals will cause a yellow-brown color

developement.

Reductive chemical could interfere with the reagent.
