Qualitative starch test paper with potassium iodide MN 616 T, intended for the rapid detection of nitrites and free chlorine, as well as other strong oxidizing agents. Designed primarily for immediate qualitative testing by spot testing or immersion. Nitrite or free chlorine oxidizes the potassium iodide present on the paper, releasing elemental iodine which reacts with the starch to produce a blue-violet coloration, indicating the presence of the oxidizing agent. The detection limit is approximately 1 mg/L for nitrite (NO2?) and 1 mg/L for free chlorine (Cl2). The color change is from white to blue-violet, and the reaction is virtually immediate. It can also be used to monitor diazotization reactions and, when properly moistened with distilled water, to detect gaseous oxidizers.

These test papers come without a color scale. With little effort, the presence of ions and other substances can be detected. The test papers change color when the concentration is above the specified limit of detection.

Test papers for criminal investigations
Peroxtesmo KM is sensitive to peroxidase and detects blood traces. Sperm traces can be detected using Phosphatesmo KM which is specific for acidic phosphatase. Both test papers are used in the investigation of crime scenes.

Test papers for milk analysis
The test paper Peroxtesmo MI allows the easy distinction between raw milk and high temperature milk. It is sensitive for the enzyme lactoperoxidase. In contrast to liquid indicators based on guaiacol, Peroxtesmo MI does not smell and comes without hazardous reagents which is convenient and safe for the user.

Test papers for oil and oil tanks
Oil test paper is recommended for the rapid determination of oil contaminations in water and soil. On contact with oil the paper turns dark blue. AQUATEC allows the easy and reliable detection of water at the bottom of petrol and fuel oil tanks. It is also suitable to measure the thickness of water layers in oil separators.
