Routine Analysis of Polar Pesticides in Water at Low Levels by Ion Chromatography

Thermo Fisher Scientific
21 Jun 2018

The analysis of polar ionic pesticides in surface and drinking water as well as food and beverages has become a controversial issue in recent years. The development of genetically modified organism (GMO) crops tolerant to glyphosate (N-(phosphonomethyl)glycine) and glufosinate ((RS)-2-amino4-(hydroxy(methyl)phosphonoyl)butanoic acid), for example, promoted the use of these broad spectrum herbicides. In addition, glyphosate is used as a crop desiccant and to suppress weeds in parks and at roadsides. Consequently, polar pesticides are found in foods as residues and in the environment as contaminants of surface waters and soils.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. PesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA. Triple Quadrupole MsChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
