综述了两性离子表面活性剂在分析检测尤其在色谱分离和毛细管电泳技术中的应用。在色谱分离中,两性表面活性剂首先被用作固定相,能很好地分离海水及雨水中的阴离子;后来随着色谱技术在生物领域的应用,两性表面活性剂又被用作流动相,即把其溶解于电解质溶液中,此流动相能很好地分离含蛋白质的生物样品。两性表面活性剂还被广泛地用于毛细管电泳中,即作毛细管壁上的动态或静态的涂层,此法既可控制电渗流,提高分离效果,又可避免蛋白质等一些样品粘在壁上,是一种较理想的生物分离技术。

Experimental and numerical analysis of high-resolution injection technique for capillary electrophoresis microchip

This study presents an experimental and numerical investigation on the use of high-resolution injection techniques to deliver sample plugs within a capillary electrophoresis (CE) microchip. The CE microfluidic device was integrated into a U-shaped injection system and an expansion chamber located at the inlet of the separation channel, which can miniize the sample leakage effect and deliver a high-quality sample plug into the separation channel so that the detection performance of the device is enhanced. The proposed 45° U-shaped injection system was investigated using a sample of Rhodamine B dye. Meanwhile, the analysis of the current CE microfluidic chip was studied by considering the separation of Hae III digested ϕx-174 DNA samples. The experimental and numerical results indicate that the included 45° U-shaped injector completely eliminates the sample leakage and an expansion separation channel with an expansion ratio of 2.5 delivers a sample plug with a perfect detection shape and highest concentration intensity, hence enabling an optimal injection and separation performance.

Detection of Novel Carbohydrate-Related Compounds in Aqueous Samples Using a Capillary Electrophoretic Profiling Method

The aim of this research was to extend an existing capillary electrophoresis (CE) method, originally developed for the determination of mono- and disaccharides, to the determination of alternative carbohydrate compounds, namely furfural and polydatin. Empirical validation confirms that this novel method can be applied for the determination of analyte concentrations from complex matrices, and the evaluation of their carbohydrate composition. It is concluded that the approach has validity as an analytical procedure and has the ability to determine industrially important analytes from a heterogeneous biological sample matrix, and thus, the method adds value to the development of large scale separation processes. However, some additional optimization is required before online applications.

Chiral Separations using Miniaturized Techniques: State of the Art and Perspectives

The separation and analysis of chiral compounds is an important topic of research, because these analytes are involved in various processes, e.g., biological, pharmacological, human health, etc. Their separation has also been recently obtained utilizing microfluidic techniques, such as capillary electrophoresis (CE), electrochromatography (CEC), and capillary/nano-liquid chromatography (CLC/nano-LC). Enantiomeric separation is mainly obtained by applying the direct resolution method, where a chiral selector (CS) is present in the separation system, either added to the mobile phase (MP) or bonded to the stationary phase or to the capillary wall. Among the several CSs used in microfluidic techniques, cyclodextrins, proteins, peptides, glycopeptide antibiotics, and modified polysaccharides are the most employed. Microfluidic techniques can offer several advantages over conventional analytical tools, e.g., high efficiency, high mass sensitivity, and reduced volumes of MP and sample. Optimized methods have been applied in different fields, such as biomedical, food chemistry, environment, pharmaceutical, etc. Excellent results have been achieved in CE and nano-LC. Although CEC can offer higher efficiency due to the use of a strong electroosmotic flow, its use is less popular than the other. This limitation can be explained with the limited number of the stationary phases (SPs) commercially available.
