Description

General description

The Spectroquant^® AOX Standard is diluted with distilled water to prepare a standard solution of an appropriate concentration. This standard solution is then analyzed using the Spectroquant^® AOX Cell Test to check the measurement procedure. AOX Standard takes the form of an aqueous solution of 4-chlorophenol with a concentration of 20 mg/l AOX.

These Spectroquant^® standards perfectly complement our ready-to-use test kits and photometers within the Spectroquant portfolio and are ideal for validating international norm methods described in e.g., ISO, EN, APHA, and EPA.
