The Determination of Dispersed Oil in Water Using Automated SPE in Compliance with OSPAR and ISO 9377-2 Methods in Norway
The Determination of Dispersed Oil in Water Using Automated SPE in Compliance with OSPAR and ISO 9377-2 Methods in Norway
15 Sept 2015Accurate measurement of dispersed oil-in-water (OIW) has become increasingly more important as international regulations are implemented, requiring off-shore platforms and refineries to demonstrate to regulators and government bodies that effective and accurate OIW monitoring is taking place, as non-conformance of these regulations can result in financial penalties. This application note provides an overview of the OSPAR-recommended method of gas chromatography and flame ionization detection (GC-FID), as described in the modified ISO 9377-2 GC-FID. The use of solid phase extraction (SPE) also eliminates many of the problems that can occur during the extraction step.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Waste WaterPetrochemicalsPetrochemicals are chemical products derived from petroleum or natural gas, essential in creating plastics, fuels, and synthetic materials.
