Determination of 1,4-dioxane in Drinking Water by Solid Phase Extraction (spe) and Gas Chromatography/mass Spectrometry (gc/ms) with Selected Ion Monitoring (sim)

Determination of 1,4-dioxane in Drinking Water by Solid Phase Extraction (spe) and Gas Chromatography/ Mass Spectrometry (gc/ms) with Selected Ion

Combined Determination of 1,4-Dioxane and Nitrosamine Contaminants in Drinking Water Using SPE and CSR-LVSI GC-MS

Global concern over the carcinogenic potential of 1,4-dioxane and several nitrosamines has resulted in increased interest in the development of more efficient testing methods for these contaminants in drinking waters. In the U.S., the current methodologies recommended for the analysis of 1,4-dioxane and nitrosamines in drinking waters are Environmental Protection Agency (EPA) Methods 522 and 52...

Combined Determination of 1,4-Dioxane and Nitrosamine Contaminants in Drinking Water Using a Single SPE Cartridge and Concurrent Solvent Recondensation– Large Volume Splitless Injection (CSR-LVSI) With EI GC-MS

Global concern over the carcinogenic potential of 1,4-dioxane and several nitrosamines has resulted in increased interest in the development of more e" cient testing methods for these contaminants in drinking waters. In the U.S., the current methodologies recommended for the analysis of 1,4-dioxane and nitrosamines in drinking waters are Environmental Protection Agency (EPA) Methods 522 and 521...

Method development for the analysis of 1,4-dioxane in drinking water using solid-phase extraction and gas chromatography-mass spectrometry.

1,4-Dioxane has been identified as a probable human carcinogen and an emerging contaminant in drinking water. The United States Environmental Protection Agency's (U.S. EPA) National Exposure Research Laboratory (NERL) has developed a method for the analysis of 1,4-dioxane in drinking water at ng/L concentrations. The method consists of an activated carbon solid-phase extraction of 500-mL or 100...

Trace-level determination of 1,4-dioxane in water by isotopic dilution GC and GC-MS.

The volatile and polar solvent 1,4-dioxane has recently been reported as a contaminant of ground and surface waters, establishing the need to determine this substance in drinking water. This investigation established that 1,4-dioxane can be determined in water by various techniques including direct aqueous injection (DAI) gas chromatography (GC) and purge and trap GC-mass spectrometry (MS).
