Stereoselective Separation of Triazole Fungicides Using the ACQUITY UPC2 System and ACQUITY UPC2 Trefoil Chiral Columns
Stereoselective Separation of Triazole Fungicides Using the ACQUITY UPC2 System and ACQUITY UPC2 Trefoil Chiral Columns
3 Aug 2015The development of analytical methods for the separation of chiral compounds is important in many areas of research, as it is well known that different enantiomers are selectively biologically active. It is estimated that 20 to 30% of pesticides on the market today have optical isomers, and there are reports that 40% of the pesticides used in China are chiral. This application note presents the enantiomeric and/or diastereomeric resolutions of 12 triazole fungicides using Waters® Trefoil Column Technology.

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.

SFC systems require injectors, pumps, columns, ovens and detectors. The SFC retention method uses a supercritical fluid, usually CO2. There are a number of different SFC detector types including UV / VIs, ECD, mass spectrometry and fluorescence.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.Chiral CompoundsPesticidesPesticides 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. SFCEnvironmental 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.Fungicides
