Volume: 100 mL.


Description

Description

The use of standard solutions can provide control of the laboratory process, increase confidence, and help provide a clear demonstration of performance to various inspectors, regulatory agencies and clients. One-parameter analysis can be performed on different analyzed samples and concentrations to confirm accuracy.

Standard solution, cobalt (2150342) from Hach. Concentration 1000 mg/L as Co (NIST).

Platform: Solution.

Summary of method: After the sample is buffered and pyrophosphate is added to mask any Fe3+, the cobalt reacts with 1-(2-Pyridylazo)-2-Naphthol indicator. The indicator forms complexes with most metals. After color development, EDTA is added to destroy all metal-PAN complexes except nickel and cobalt. This method is unique because both nickel and cobalt can be determined on the same sample. Single-wavelength instruments, such as the Pocket Colorimeter, cannot differentiate between nickel and cobalt.
