The multiple-ion detection technique extends the determination to include related degradation products and considers four separate ion ratios and retention times fit. This procedure does not suffer from the interferences previously reported by Laseter et al.

Characterization and Determination of Linear Alkylbenzenesulfonates in Environmental Water Samples by High-Performance Liquid Chromatography with a Hydrophilic Polymer Column and Electrospray Ionization Mass Spectrometric Detection

“…[4][5][6] However, some derivatization steps to convert LAS into a volatile compound 7,8 are unavoidable for GC procedures, because LASs are not volatile enough to permit direct measurement by GC. LC has widely been applied to the determination of LAS in various environmental samples without any derivatization using ultraviolet (UV), 9-11 fluorescence (FL), [12][13][14][15][16] and MS [17][18][19] detection. Nakae et al 12,13 obtained an excellent separation of many LAS components (homologues and isomers) by reversed-phase chromatography with FL detection.…”

They determined LASs at the sub-ppm level in river water samples without any pretreatment.…”

Analysis of Surfactants in Environmental Samples by Chromatographic Techniques

“…The presence of a benzene group also facilitates the use of UV for identifying some specific cationic surfactants such as benzalkonium chlorides (BACs) [97]. Moreover, HPLC coupled to FL detector was employed by Natkae and co-workers [131] to achieve partial separation of positional isomers and obtain information on the alkyl chain distributions of LAS in river water samples. However, aliphatic surfactants (e.g., AEOs and AES) have not been monitored so much due to their lack of UV absorbance or fluorescence.…”

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.…”
