| Use of Vario H Powder Packs |
| Chlorine, free and total |
- Free Chlorine
Free Chlorine (Hypochlorous Acid and Hypochlorite Ion) oxidizes DPD. The reactions is pH dependent. DPD and a buffer system (pH 6.3-6.5) cause a magenta colour in the presence of Free Chlorine. Both, our Vario H Powder and Hach® Powder handle high levels of hardness without precipitation.
- Total Chlorine
Potassium Iodide is used to determine combined chlorine forms. Chloramines oxidize the iodide to iodine; the liberated iodine reacts with DPD. Both, Sigma-Aldrich Vario H Powder and Hach® Powder contain DPD, Potassium Iodide and a buffer system.
