Extraction of Semivolatile Organic Compounds from Water Using AutoTrace 280 Solid-Phase Extraction Cartridges

30 Nov 2016

This application note describes the use of the Dionex AutoTrace 280™ instrument for extraction of semi volatile organic compounds from water samples. With the Dionex AutoTrace 280 system, the compounds of interest are trapped on SPE adsorbents, then eluted with liquid solvents to generate an extract that is ready for analysis.

Thermo Scientific™ Dionex™ AutoTrace™ 280 Solid-Phase Extraction Instrument

Thermo Fisher Scientific

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

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.Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Environmental 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.Solid Phase Extraction (SPE)Solid phase extraction (SPE) is a sample preparation technique used to separate and concentrate analytes from complex mixtures. It is widely used in environmental, pharmaceutical, and clinical analysis. SPE provides higher sensitivity and selectivity compared to traditional liquid-liquid extraction methods, making it essential for accurate and reproducible results. Explore SPE tools and systems in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Semi Volatile Organic CompoundsSemi volatiles organic compounds (SVOCs) are a groups of compounds that have a low boiling point and evaporate above room temperature. SVOCs include phenols and polynuclear aromatic hydrocarbons (PAH).
