Drugs & Metabolites

Micropollutants, such as pharmaceutical and hormone-active substances and their metabolites, constantly contaminate worldwide municipal wastewater. They usually enter the wastewater after being excreted in urine. A fraction of these substances remains and can be detected in surface water in relevant concentrations - if an analytical reference material is available. The detection is challenging but highly important, as these pollutants can damage the health of animals and plants when entering drinking water sources (lakes, rivers, groundwater,..).

For greater protection of the environment, we gladly offer analytical standards and reference materials for convenient detection of APIs and their metabolites in wastewater. Our analytical reference materials are certified by quantitative nuclear magnetic resonance (qNMR), and the measured value is traceable to NIST standard reference materials (ISO / IEC 17025).
