Water treatment is required to maintain effluent compliance with standards established by regulatory bodies. Learn about the stages of wastewater and process water treatment along with the corresponding analytical testing methods.
Soil and groundwater testing are crucial to avoid adverse impact on the environment and human health. Learn about the importance of solid waste management and methods used for soil and groundwater testing for heavy metals and other environmental pollutants.
Filtration separates substances based on physical or chemical properties. Lab samples are routinely filtered before analysis to reduce sample complexity and increase analyte purity. This allows scientists to generate higher quality analytical results.
Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
Solid phase extraction (SPE) is a technique used for rapid, selective sample preparation and purification prior to chromatographic analysis (e.g. HPLC, GC, TLC). SPE is used to exchange sample matrices, concentrate analytes, and remove interferences and contaminants to improve data and protect the analytical column.
