Analytical Standards and New SupelMIP SPE Cartridges The mycotoxin patulin is often found in rotten apples. It is mostly produced by Aspergillus, Penicillium and Byssochlamys and shows a variety of short-term and long-term effects in animal studies, ranging from gastrointestinal problems and neurotoxicity to genotoxicity and teratogenicity. Therefore, many countries set limits for patulin ...
In this application, a solid phase extraction (SPE) method was developed using Supelclean™ EZ-POP NP SPE for extraction and a small silica gel cartridge for additional cleanup. ...
With the rise in popularity of this extraction technique and due to its reliable multiresidue methods it has driven the need for automation of the QuEChERS extraction to increase productivity and throughput. The AutoMate-Q40 streamlines the QuEChERS method from adding Acetonitrile (ACN) and buffering salts, shaking, mixing, centrifugating the sample, transferring ...
Abstract With the rise in popularity of QuEChERS, due to its reliable multiresidue methods it has driven the need for automation of the QuEChERS extraction to increase productivity and throughput. The AutoMateQ40 streamlines the QuEChERS method from adding Acetonitrile (ACN) and buffering salts, shaking, mixing, centrifugating the sample, transferring to a dispersive ...
Abstract The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities. ...
The AutoMate-Q40 instrument streamlines the QuEChERS method, from adding Acetonitrile (ACN) and buffering salts, shaking, mixing, centrifuging the sample, transferring to a dispersive solid phase extraction (dSPE) tube, and finally measuring and delivering the extract. ...
We used a QuEChERS-based sample preparation method and gas chromatography-time of flight mass spectrometry (GC-TOFMS) for analyzing pesticides. Several different dispersive solid phase extraction (dSPE) formulations in ready-to-use tubes were tested to determine which provided an optimum balance of sample cleanup along with ...
The selectivity of in-tube extraction by PTFE tubing vis-a-vis mini-column SPE has been evaluated for preconcentration and cleanup of PACs in their natural matrix, and has been found to effectively remove many polar analytes such as nitrogen containing aromatic heterocyclic compounds, anilines, phenols and certain organophosphorus pesticides. ...
Recovery rates for polar analytes, including carbamate and thiourea pesticides, are higher and less variable with ENVI-Carb carbon-based solid phase extraction tubes than with C8- or C18- silica-based tubes. Independent investigators found ENVI-Carb tubes to be an effective part of sample cleanup ...
ENVI-Florisil solid phase extraction tubes meet the requirements for pesticide recovery from water, sediment, and soil samples taken from hazardous waste sites, as described in US EPA Contract Laboratory Program methodology. ...
