“…Different CE-techniques like CGE or CIEF were developed over the last years and are currently used intensively in a similar manner to classical gel electrophoresis [362] in the fields of human genomics and proteomics [363,364]. For example, gene expression of single cells [359] by CZE allows separation of the analytes based on their charge-tomass ratio, establishing new possibilities for the characterization of unknowns in complex mixtures (such as natural compounds and heterogeneous/polydisperse natural organic matter (NOM) [5]). The possible separation strategies are the basis of many studies involving the understanding of mixture such as in proteomics [365], metabolic profiling or metabonomics [366], especially when combined to an MS using gentle detection by ionization techniques such as ESI.…”

“…Additionally, note that identical injection times with different column inner diameters or lengths lead not only to different column volumes but also to different local sample concentrations when passing the detector -an important fact when coupling to MS. This is also important when assaying analytes with concentration-dependent aggregation properties such as polymeric materials or natural organic matter [5].…”

Capillary electrophoresis -mass spectrometry: 15 years of developments and applicationsSince its introduction in 1987, capillary electrophoresis-mass spectrometry (CE-MS) has developed to a well accepted multidimensional analytical approach complementary and/or competitive to classical MS-hyphenated separation techniques. The threefold combination of rapid developments of an exceptional separation technique, of selective mass detection possibilities, and of very mild ionization modes first allowed these progresses. This article shows the CE specificities that need to be well controlled/known, compared to classical and more routinely used liquid chromatography in the light of its coupling to MS. The major trends and developments over the last 15 years and most of the reviews and applications found in ISI Web of science and publisher databases are presented in a tabulated way. The reader can thus rapidly find existing CE-MS analysis techniques in his field of research and application (forensics, environment, bioanalytics, pharmaceutics, and metabolites).

“…Also, mobile phase interactions cannot be excluded. Lin et al (2007) used CE for the sizing of engineered Au and Au/Ag nanoparticles and Schmitt- Kopplin and Junkers (2003) have used CE in the characterization of humic substances and other natural organic matter.…”

Nanotechnology is developing rapidly and, in the future, it is expected that increasingly more products will contain some sort of nanomaterial. However, to date, little is known about the occurrence, fate and toxicity of nanoparticles. The limitations in our knowledge are partly due to the lack of methodology for the detection and characterisation of engineered nanoparticles in complex matrices, i.e. water, soil or food. This review provides an overview of the characteristics of nanoparticles that could affect their behaviour and toxicity, as well as techniques available for their determination. Important properties include size, shape, surface properties, aggregation state, solubility, structure and chemical composition. Methods have been developed for natural or engineered nanomaterials in simple matrices, which could be optimized to provide the necessary information, including microscopy, chromatography, spectroscopy, centrifugation, as well as filtration and related techniques. A combination of these is often required. A number of challenges will arise when analysing environmental and food materials, including extraction challenges, the presence of analytical artifacts caused by sample preparation, problems of distinction between natural and engineered nanoparticles and lack of reference materials. Future work should focus on addressing these challenges.

“…Many papers were published on the real possibilities of CE in the field of HS as presented in-depth in the tabulated review by SchmittKopplin and Junkers [4]. Several studies have reported the use of CE for the fingerprinting and characterization of HS and natural organic matter (NOM) [177][178][179][180][181][182][183][184].…”
