Forensic Toxicological Determination of Surfactant by Liquid Chromatography/Electrospray lonization Mass Spectrometry and Liquid Chromatography/Electrospray lonization Tandem Mass Spectrometry.

Quantitative analysis of surfactant deposits on human skin by liquid chromatography/electrospray ionisation tandem mass spectrometry

“…Moreover, they are non‐volatile and non‐UV‐absorbing compounds; therefore, the application of conventional chromatographic methodologies and spectroscopic detection systems does not allow for the development of sensitive and selective assays. However, MS‐based analytical protocols offer improved selectivity and sensitivity, and they have been successfully applied to the detection and quantitation of surfactants in complex mixtures, such as in wastewater treatment,21 quality control of pharmaceuticals18 or forensic applications 27…”

Simple and Rapid Determination of Linear Alkylbenzene Sulfonates by In-Tube Solid-Phase Microextraction Coupled with Liquid Chromatography

“…A large variety of analytical techniques have been proposed for determining LAS, such as molecular absorption spectrophotometry, liquid chro- matography (HPLC) with ultraviolet (UV) 12,13) or fluorescence detection, 14,15) liquid and gas chromatography (GC) 16,17) with mass spectrometry (MS) [18][19][20] and biosensors. 21) However, they are tedious, complex, time consuming and require large amounts of organic reagents.…”

Release of surfactants from organo-modified montmorillonite into solvents: Implications for polymer nanocomposites

“…Meanwhile, the measurement should be relatively rapid, which is critical for realtime transport studies. There are some studies on the analysis of surfactants by liquid chromatography (Ferrer and Furlong, 2001;Nishikawa et al, 2003;Li and Brownawell, 2009); however, the separation of various components in the quaternary alkylammonium surfactants was difficult, and the analysis time was long in order to achieve a good separation, which will make the method difficult to use for migration studies. In addition, the analysis of surfactant was usually from environmental samples (sewer water, soil, etc.)…”
