N. N-Diethyl-p-phenylene-Diamine indicator and a buffer are mixed with the sample. Free available chlorine oxidizes the DPD indicator reagent at a pH between 6.3 and 6.6 to form a magenta colored compound. The intensity of the resulting color is proportional to the concentration of chlorine in the sample. The purpose of the buffer solution is to maintain the proper pH.\u003c\/p\u003e\n\u003cp\u003eIn total chlorine measurement (free available chlorine plus combined chloramines). potassium iodide is added. A pH of 5.1 is required for this reaction. Thus total chlorine measurements require a different buffer solution containing potassium iodide. Once the chemical reaction is completed. the optical signal at 555 nm is compared to the signal measured through the sample before the reagents were added. From these measurements chlorine concentration is calculated and shown on the display.\u003c\/p\u003e\n\u003cp\u003eIndicator and buffer reagent bottles are placed directly into the instrument case.
