April 2012 Subscribe Go to Application Note Library Sensitive Detection of Pyrethroids in Surface Water and Sediment Stephan Baumann, Agilent Technologies Explore a new method for sensitive detection limits for pyrethroids as low as 0.05 ppt in water samples and 0.02 ppb for sediment.   Optimizing Detection of Steroids in Wastewaters Using the Agilent 6490 LC–MS-MS System with iFunnel Technology Neil Cullum, Agilent Technologies Taking full advantage of the enhanced sensitivity of the Agilent 6490 Triple Quadrupole LC–MS system requires optimization of method parameters derived on other triple quadrupole platforms.   Analysis of Herbicides Using HPLC with Low Temperature Evaporative Light Scattering Detection Stephen Ball, Agilent Technologies Explore how the 380-ELSD evaporative light scattering detector was used to determine the effect of varying the evaporation temperature during the analysis of a mixture of herbicides with different volatilities.   Automated Clean-up of PCB Extracts from Waste Oil Using the Agilent 7696A Sample Prep WorkBench Frank David, Bart Tienpont, and Karine Jacq, Agilent Technologies Solid waste, including petroleum based waste oils, transformer oil, or mineral oils are screened for the presence of polychlorinated biphenyls (PCBs).   Analysis of Organophosphorus Pesticides with Agilent 7820 Gas Chromatograph Flame Photometric Detector Agilent Technologies The 7820 series GC equipped with a flame photometric detector (FPD) provides high sensitivity, good linearity, and stability for the analysis of organophosphorus pesticides.   Measurement of Antibiotics in Environmental Waters Using LC-QQQ and Fully Automated Online Enrichment Agilent Technologies After excretion, antibiotics and pharmaceuticals and personal care products (PPCPs) ultimately enter waste-water treatment plants with subsequent discharge into surface water and the aquatic environment. The analysis of PPCPs in water is accomplished using an Agilent LC-QQQ.   Analysis of PAHs in Soil According to EPA 8310 Method with UV and Fluorescence Detection Sonja Volk and Angelika Gratzfeld-Huesgen, Agilent Technologies This application note describes a reproducible method according to EPA 8310 for sample preparation and HPLC analysis of PAHs in soil with good recovery rates and detection limits that fulfill regulatory requirements.   Single Stage Extract Cleanup in Pesticides Determination Using Agilent EnviroPrep Greg Saunders and Ben Maccreath, Agilent Technologies High performance gel permeation chromatography with Agilent EnviroPrep provides a simple, one stage, clean-up procedure for the determination of pesticides in a variety of organic matrices, such as soil and animal tissue.   Fast Analysis of PAHs Using Low Thermal Mass and Capillary Flow Technology Frank David, Agilent Technologies Cycle time for GC–MS analysis of PAHs in soil and sediment samples was improved dramatically through the combined use of a narrow- bore column installed in an LTM module and capillary column backflushing with QuickSwap.   Direct Aqueous Analysis of Pharmaceuticals in Water at ppt Levels by LC–MS-MS with Ion Funnel Technology Imma Ferrer and E. Micheal Thurman, Agilent Technologies Pharmaceutical residues in water may have an adverse impact on humans, wildlife, and fish. Therefore, sensitive and reliable analytical methods are necessary to detect these compounds at trace levels.
