Chlorine

Description

Chlorine is measured using the DPD colorimetric method (US EPA 4500-CI G and ISO 7393-2 accepted method). The determination ranges of the analyzer vary from trace μg/L to 200 mg/L Cl2 using the (optional) internal dilution module.

Method

This parameter has more than one analytical method. Choose one below.

Chlorine-containing samples are reacted with N,N-diethyl-p-phenylenediamine sulfate in the presence of a suitable buffer. The indicator and buffer are added and react with chlorine to produce a pink color. This compound is measured at 525 nanometers.
