Determination of Monocrotophos, Diazinon, Malathion, EPN, and Methamidophos from Aqueous Samples
Determination of Monocrotophos, Diazinon, Malathion, EPN, and Methamidophos from Aqueous Samples
24 Feb 2016These are commonly used organophosphorus pesticides (OPP) in many parts of the world in agriculture for the control of insects and aquatic pests. Traces of these compounds are being found in food and water sources, and so their levels are closely monitored in waste water and drinking water. Many methods have been developed for this measurement, this application note discusses a technique called Salting-out Liquid-Liquid Extraction (SALLE).

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Sample ManagementSample management systems include sample storage devices such as freezers and plate storers, sample environment enclosures and sample organization, retrieval and sorter systems. Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.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.Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
