Standards and Reagents

AccuSPEC COD Digestion Tubes use standard 16 mm tubes that have been prefilled with the digestion reagent. The solution contains mercuric sulfate (HgSO4) to remove up to 2000 ppm of chloride interference.

COD Digestion Tubes

Simply aliquot 2 ml of sample directly to the prefilled COD digestion tube, replace the screw cap, and mix by inverting the tube. Place the digestion tubes in the DigiPREP CUBE, or the Automated EasyPREP COD-200, set to 150 °C. Heat for 2 hours, allow samples to cool, then measure in a spectrophotometer at the appropriate wavelength. For more information on the EasyPREP COD-200, click here.
