Beschreibung

General description

Method: colorimetric, DPD, with color-disk comparator 0.15 - 0.35 - 0.5 - 0.7 - 1.4 - 2.7 - 5.0 - 7.0 - 10 mg/l O₂ MQuant^®

The MQuant^® Ozone test (formally MColortest^®) measures the content of ozone in:

• Drinking water
• Wastewater
• Process water
• Disinfectant solutions
• Swimming-pool water

This test is not suited for seawater.

Method
In weakly acidic solution ozone reacts with dipropyl-p-phenylenediamine (DPD) to form a red-violet dye. The ozone concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation. The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
Using the refill pack 1.18759 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.

Application

• Air Quality Monitoring: Ozone tests are crucial for monitoring air quality, particularly in urban and industrial areas where ozone pollution is a significant concern. These tests help in assessing the concentration of ozone in the atmosphere and its impact on public health and the environment. Recent research has reviewed various analytical methods applied for ozone gas detection, emphasizing their importance in environmental protection and regulatory compliance (Petruci et al., TrAC Trends in Analytical Chemistry, 2022).


• Environmental Research: In environmental studies, ozone tests are used to investigate the sources and distribution of ozone in different ecosystems. These tests are vital for understanding the chemical reactions that produce ozone and its role in atmospheric chemistry. Advanced analytical techniques, such as portable deep-UV absorption sensors, are employed to measure ozone levels accurately, providing detailed insights into environmental ozone dynamics (Zheng et al., Trends in Environmental Analytical Chemistry, 2023).
