A Rapid LCMS Method for Evaluation of EPA 1694 and 6810 Contaminants in Drinking Water
A Rapid LCMS Method for Evaluation of EPA 1694 and 6810 Contaminants in Drinking Water
6 Jul 2016This application note describes a comprehensive method for evaluating multiple steroids, pharmaceuticals and personal care products at picogram per milliliter levels in drinking water using ultra-fast LCMS-MS. Most of these chemicals, also known as contaminants of emerging concern (CECs), enter the environment through treated and raw sewage and are detrimental to the aquatic organisms at picogram per milliliter levels. Early detection for these CECs was performed using GC-MS but more recently LC-MS has become more popular for detecting low levels of these contaminants in wastewater.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. 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.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.

These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.CosmeticsEnvironmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.PharmaceuticalsPharmaceuticals are medicinal drugs used in healthcare to diagnose, prevent, cure and treat illnesses. Pharmaceuticals that are excreted after use appear in wastewater and can have detrimental effects on the environment.SteroidsWater 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).
