Click here Sample Prep Extraction of Loperamide and N-Desmethyl Loperamide from Blood This note outlines a simple three-step method for the extraction of Loperamide and N-desmethyl Loperamide from blood using UCT’s Clean Screen® XCEL I SPE columns. Extraction of Pesticides from Cannabis This application note demonstrates rapid automated extraction and LC/GC analysis of over 400 pesticides from cannabis flower. AF4-MALS for Industrial Lignosulfonate Analysis Eliminating laborious sample preparation, field-flow fractionation greatly facilitates the absolute characterization of lignosulfonates by multi-angle light scattering. Pharmaceuticals Determination with HLB-based SPE Disk Thin, dense, and soft HLB-based SPE disks were tested for the analysis of drug compounds such as penicillin, sulfonamides, and tetracyclines in water according to EPA method 1694.   GC–MS TO-17 by CDS 7550S Thermal Desorber The sensitivity of the CDS 7550S coupled to a GC–MS for the analysis of TO-17 VOCs ranging in volatility from Dichlorodifluoromethane to Naphthalene is demonstrated.   LC Automated SFC–MS Method Development for Pharmaceuticals This study demonstrates fast and comprehensive method development with Agilent Method Scouting Wizard software for the analysis of pharmaceutical compounds by SFC–MS. A New Fused-Core® Stationary Phase for Challenging Isomer Separations Built on Fused-Core® particle technology, the new HALO® C30 offers high shape selectivity for hydrophobic, long-chain, structurally related isomers. Analysis of Apramycin Sulfate Post-column derivatization with Ninhydrin reagent for analysis of 3-hydroxyapramycin, lividamine, caerulomycin, 2-deoxystreptamine as impurities in Apramycin Sulfate. Cost-Effective Decontamination of Cannabis and Hemp Extracts Remove all pesticides and other contaminants from cannabis and hemp extracts without significant cannabinoid loss using proprietary, cost-effective KDM method. Aflatoxin Assay Using a Low-Cost Fluorescence Detector An isocratic HPLC method for the analysis of aflatoxins. Uses the DFL-10 ( filter fluorescence detector) with a photochemical reactor to improve sensitivity.   GC Analyze More Semivolatile Samples per Shift Using Split Injection Using split injection can increase sample throughput for semivolatiles analysis because it provides faster oven cycle times due to the use of higher initial oven temperatures.
