Compatible Devices : EasyPlus UV/VIS and UV/VIS Excellence Spectrophotometer
The Environmental Protection Agency (EPA) has standards for UV/Vis spectroscopy, particularly for water and wastewater analysis. EPA methods for UV/Vis measurements are focused on the detection and quantification of pollutants, such as organic compounds, metals, and nutrients, in environmental samples. The EPA provides approved methods for UV/Vis measurements in its Method 1100 series, which includes guidance on instrument calibration, quality control, data analysis, and reporting. These standards are important for ensuring the accuracy and reliability of environmental monitoring data, which is used to assess the health of ecosystems and protect public health.
