"Automated enzymatic, colorimetric analysis is a great method to obtain fast, accurate results," Burdett says.
Over the past few years, a rise in demand for discrete analyzers has been registered due to their compact design, effective sample & reagent mixing, colorimetric analysis and limited cross contamination, all of which have been leading to the generation of large revenues in the discrete analyzers market.
For many years, the basic analytical method being used to determine the concentration of aluminum in industrial wastewater was the colorimetric analysis. It is based on the well-recognized ability of aluminum to form colourful complexes with organic compounds such as eriochrome cyanine R (3"-sulfo-3,3'-dimethyl-4-hydroxyfuchson-5,5'-dicarboxylic (ECR)) (Figure 1), catechol violet [5], or aluminon [6].
The Endress+Hauser Liquiline CA80TP phosphorus analyzer uses a thermal digestion technique, along with colorimetric analysis requiring a small quantity of reagents, to monitor industrial wastewater; it measures phosphorus in ranges from 0.05 to 10mg/L or 0.5 to 50mg/L.
This procedure was conducted because the reflection-based colorimetric analysis normally utilized white light illumination.
