Reagent set Ultra Low Range Hardness determination by the Chlorophosphonazo method. Hach Method 8374. Range: 4 - 1000 ug/L Ca & Mg as CaCO₃ with the pour-thru cell (DOC316.53.01045); 8 - 1000 ug/L Ca & Mg as CaCO₃ with plastic cell (DOC316.53.01044).

Calcium and magnesium mix equally with the Chlorophosphonazo Indicator to give a complex with color which absorbs light very strongly at 669 nm. One drop of the CDTA reagent breaks up this complex. The decrease in color is proportional to the amount of calcium and magnesium in the sample (as CaCO₃). The measurement wavelength is 669 nm. Chlorophosphonazo reagent solution in part number 2603101 is packaged in a 500 mL bottle (part number 2589549) that is ideal for use with Hach's Pour-Thru Cell. Approximately 250 tests.

Applications:

  • Groundwater
  • Membrane Protection
  • Municipal Water
  • Pre-Treatment
  • Source Water
  • Surface Water

Benefits

Convenience

Rapid Liquid methods utilize liquid reagents, bottletop dispensers and pour-thru cells to provide simplified testing.

Performance

Since the pour-thru cell provides a stationary optical system, Rapid Liquid methods typically provide better precision than methods that require movement of sample cells.

Efficiency

Rapid Liquid methods are ideal for high-volume testing.
