Extracting Organochlorine Pesticides from Water With Atlantic™ HLB-M Disks
25 Mar 2011This application note by Horizon Technology establishes a solid phase extraction (SPE) procedure to streamline the sample preparation process for determining organochlorine pesticides from water. Using SPE allows the use of acetone and hexane as the extraction solvents which generally reduce the amount of interferences that are extracted and improves the signal-to-noise ratio within the analysis phase of sample processing.

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.
