Availability: Order only
Phosphate Standard Solution, 100 mL.
Сoncentration 15 mg/L PO4.
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.
Nitrite standard solution (1424342) from Hach for one-parameter water analysis. For treated and natural waters. For accuracy checks in Phosphate determinations.
Quantity: 100 mL.
Summary of Method: Orthophosphate reacts with molybdate in an acid medium to produce a phosphate/molybdate complex. Ascorbic acid then chemicaly reduces the complex, which makes an intense molybdenum blue color. Results include orthophosphate in the sample, plus a small fraction of condensed phosphate that can be hydrolyzed to orthophosphate during the test. The measurement wavelength is 880 nm (710 nm in DR1900 instruments).
