AN72333: Determination of Adsorbable Organic Halogen in Wastewater using a Combustion Ion Chromatography System

Instrument Type: IC

This application note demonstrates that AOX can be precisely and accurately determined in wastewater using combustion ion chromatography. Analysis was automated using the Mitsubishi AQF–2100H system in combination with the Dionex Integrion HPIC system with a Dionex IonPac AS18-4μm column.

AN815: Automated Solid-Phase Extraction (SPE) of Waste waters and Surface Waters Using the Thermo Scientific Dionex AutoTrace 280 SPE Instrument for EPA Method 608

Instrument Type: Automated Sample Prep

EPA Method 608 uses liquid-liquid extraction by separatory funnel combined with gas chromatography and electron capture detector for the analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in municipal and industrial waste water. Unlike the drinking water methods, however, analysis of waste waters and the streams they flow into, need to contend with particulates. The Thermo Scientific™ Dionex™ AutoTrace™ 280 instrument has features that allow analysis of samples even with high amounts of suspended solids and is suitable for use in EPA Method 608.

AB876: Automated Solid-Phase Extraction (SPE) of Wastewaters and Surface Watersfor Polyaromatic Hydrocarbons and Phthalates — Modification of EPA Method 625

Instrument Type: Automated Sample Prep

EPA Method 525.2, Determination of Organic Compounds in Drinking Water by Liquid-Solid Extraction and Capillary Column Gas Chromatography/Mass Spectrometry, can be used as a basis for developing a liquid-solid extraction method for EPA Method 625, Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater. Unlike the drinking water methods, however, analysis of wastewaters need to contend with particulates. The AutoTrace™ 280 Solid-Phase Extraction (SPE) instrument has features that allow analysis of samples even with high amounts of suspended solids.

AN1080: Automated Solid-Phase Extraction of Linear Alkylbenzene Sulfonatein Wastewater Using a Weak Anion-Exchange Cartridge Followed by HPLC with UV Detection

Instrument Type: HPLC

Surfactants are the major active ingredients of laundry detergents. Anionic surfactants account for 60% of surfactant used in the U. S. Linear alkylbenzene sulfonate (LAS) is an anionic surfactant. It is a mixture of closely-related isomers and homologues, each containing an aromatic ring sulfonated at the para position and attached to a linear alkyl chain. This application provides a complete workflow method for the extraction and analysis of LAS is waste water samples.
