Nonionic surfactants such as Triton X-100 (TX-100) are comprised of a mixture of oligomers with a varying degree of length in the ethoxylate chain. The development of chromatographic methods for resolution of the various oligomers of TX-100 is of environmental importance, and can be useful for quality control and characterization in industrial manufacture. Capillary electrochromatography (CEC) is fast becoming a capable separation technique that combines the benefits of both high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE). This report presents a novel CEC method for separation of the various TX-100 oligomers. A comparison of monomeric vs. polymeric stationary phases for separation of TX-100 was conducted. Since the oligomers of TX-100 were better resolved on a monomeric phase as compared to polymeric phase, a systematic mobile phase tuning was performed utilizing a monomeric CEC-C18-3 microm-100 A stationary phase. Various mobile phase parameters such as acetonitrile (ACN) content, Tris concentration, pH, voltage, and temperature were manipulated in order to achieve the optimum separation of oligomers in less than 30 min.

“…To overcome this limitation, the aliphatic amines are derivatized or tagged with some strongly absorbing chromophore [98]. Except the following traditional methods, some newly fluorescence/ultraviolet reagents, such as HTFA for chromium, H(FHD) for beryllium and lanthanide, DNBC for 4,4′-methylenebis (2-chloroaniline) [99], 1-NC for alcohol ethoxylate (Brij 56), and 1-hexadecanol [100], have been developed with in vial derivatization combined with DI or HS SPME and HPLC or LC analysis.…”

“…In-port derivatization techniques in GC are used for analyzing perfluorocarboxylic acids [166] and linear alkylbenzensulfonates (LASs) [62]. Moreover, post-column photochemically induced fluorimetry derivatization and fluorescence detection by HPLC are developed for the determination of phenylurea herbicides [169], pyrethroids [170], an alcohol ethoxylate (Brij 56), and 1-hexadecanol [100].…”

Solid-phase microextraction (SPME) is a solvent-free sample preparation technique using a fused-silica fiber coated with an appropriate stationary phase. Derivatization is often necessary to determine substances with poor chromatographic behavior, high reactivity, and/or volatility or thermal instability. SPME derivatization technique can be operated under different combined modes and may be influenced by factors such as sample matrix, SPME, derivatization, and desorption condition. Combined with derivatization, HS-SPME, DI-SPME, membrane-protected SPME, and in-tube SPME have been applied to the analysis of a vast amount of chemicals, i.e., aldehydes and acetone, amines, organic acids, phenolic compounds, pesticide, metal and organic metal species, and pharmaceutical and personal care products (PPCPs) in a wide range of environmental matrices, including air, water, soil, and sediment samples. This chapter reviews the mode and method development of the derivatization technique, the derivatization reagents, and reaction mechanism, as well as its applications in environmental analysis.

“…CW/TPR enabled the best extraction of the analytes, with linearity in the range 100-0.1 mg mL -1 , a detection limit of the order of 1 µg L -1 at a signal to noise ratio of 3 (UV detection), and preservation of the surfactant oligomer distribution of the original sample. SPME with in fiber, on-line derivatization for HPLC (fluorescence detection, FD) was described for the first time by Aranda and Burk [26] for the determination of Brij 56, an alcohol ethoxylate surfactant. A high detection limit and a narrow dynamic range were obtained, however.…”

Solid-phase microextraction (SPME) is a technique for extraction of organic compounds from gaseous, aqueous, and solid matrices. SPME is rapid and simple, ideal for automation and for in situ measurements, and no harmful solvents are needed. The principle of SPME involves equilibration of the analytes between the sample matrix and an organic polymeric phase coated on a fused-silica fiber. SPME is traditionally combined with analysis by gas chromatography (GC) and this combination has proved sensitive, accurate, and precise for quantitative analysis of different classes of volatile compound. More recently SPME has been coupled with liquid chromatography to widen its range of application to non-volatile and thermally unstable compounds also. This article reviews the status of SPME coupled with liquid chromatography. It focuses on different applications of the technique, e.g. environmental samples, biological fluids, and food samples, to show that SPME-HPLC has great potential in the analysis of a wide range of compounds in different matrices.
