Taylor Midget Comparator Test Kit, Chlorine (free, total), 0.1-2.0 ppm
| Description of Tests | |||||||||||||
| |||||||||||||
Chlorine is used as a sanitizer, oxidizer, and bleaching agent in many commercial, industrial, and recreational applications. Colorimetric methods employ either N,N-diethyl-pphenylenediamine (DPD) for testing free and total chlorine or orthotolidine (OT) for determining total chlorine only. Titrations use either the ferrous ammonium sulfate (FAS-DPD) method or the iodometric method for testing free and combined chlorine. The FAS-DPD method is popular with people who have difficulty matching shades of red, as its endpoint is signaled by a distinct change from a color to colorless.
Combined chlorine (CC) can be determined by subtracting the free chlorine (FC) reading from the total chlorine (TC) reading: TC - FC = CC.
Note: These tests are limited to on-site analysis. High chlorine, usually over 10 ppm, may partially or totally bleach out DPD indicator and may turn OT indicator dark brown; if this happens, the sample should be diluted and the test result multiplied by the appropriate factor. Bromine, iodine, and oxidized manganese will register as chlorine.
