Determination of Pesticide Residues in Drinking Water using Automated Solid-Phase Extraction and Gas Chromatography with Nitrogen Phosphorus Detection

The Thermo Scientific™ Dionex™ AutoTrace™ 280 Solid-Phase Extraction (SPE) instrument is a powerful, high-throughput workstation dedicated specifically for automating SPE. The Dionex AutoTrace 280 instrument automates the cartridge or disk conditioning, sample loading, rinsing, and eluting steps for large volume aqueous solution extractions (20 mL to 20 L).The unit can process up to six samples in parallel, automatically conditioning, washing, and eluting SPE cartridges or disks with a choice of up to five reagents. The unit also segregates aqueous and solvent waste using separate waste lines for efficient, cost effective waste handling.AutoTrace 280 Solid-Phase Extraction Instrument Features: Use SPE technology for liquid-liquid extraction Automated sample loading of liquids onto SPE cartridges Automated eluting of SPE cartridges with organic solvent Closed systems with a fan to vent solvent vapors Positive pressure loading and elution of samples and solvents Benefits: Reduced solvent usage and elimination of glassware Does not require technician involvement to maintain a reservoir of liquid in the SPE cartridge Does not require technician involvement to control the flow of organics solvent through the SPE cartridge No hood required Provides constant flow of liquids through SPE cartridges

The Thermo Scientific TRACE 1300 Series GC offers the most versatile gas chromatograph platform in the market, with unique "instant connect" modularity for ground-breaking ease of use and performance, setting a new era in GC technology.The Thermo Scientific TRACE 1300 Series GC is the ideal budget-conscious investment for the basic routine laboratory when lower operator expertise requires ease of use with minimal instrument interaction. Its simplified user-interface is also ideal for 24/7 operations that require single-button start/stop/maintenance local interactions while maintaining full programmability through the networked control software.Interchangeable modules free your laboratory from the challenges and constraints of the past. Remove the complexity and eliminate the need for specialized service assistance or new system requirements with modular injectors and detectors.Thermo Scientific Trace 1300 Series GC Features: Analyze dirtier matrices with minimum cleanup using the system's robust injector technology Analyze trace concentrations with smaller injection amounts and minimum preconcentration results using enhanced detector sensitivity and micro-volume technology Protect system components and reduce run time and maintenance using optional backflush capabilities Shorten sample cycle times using low thermal mass injectors and detectors and fast oven technology Automate your entire workflow—from pipetting to injection—using a full range of sample handling options Streamline and speed up data analysis using Thermo Scientific™ Dionex™ Chromeleon™ Chromatography Data System (CDS) software Expands easily from single-channel to multi-injector/detector GC configurations Reduces training and startup time with simplified installation, plug-in components, minimal local control and intuitive Chromeleon software Minimizes downtime with easy-access, tool-free modules Reduces operational costs by allowing use of standard consumables Saves energy with low thermal mass and quick start-up Minimizes sample and solvent consumption with micro-volume sample capability Modular design lets you easily reconfigure to meet changing requirements
