Determination of Melamine Residue in Water Samples by UPlC/MS/MS

13 May 2013

Since both the drinking water and the food chain may cause a direct or indirect impact on human health, it is important to carry out the study on the analysis method of melamine residue in water samples. This application note describes the determination of melamine residue in water samples using UPLC/MS/MS.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Food ContaminationFood contamination refers to the presence of harmful substances or pathogens in food, posing risks to human health. Contaminants can be biological, chemical, or physical, and their detection is crucial for ensuring food safety. Advanced testing methods like PCR, chromatography, and spectroscopy are used to identify contaminants in food products. Browse our peer-reviewed product directory to find the best solutions for food contamination detection, compare products, check reviews, and get pricing directly from manufacturers.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Melamine
