“…However, it must be considered that not all commercial apparatuses can be used because, due to bubble formations during runs, an external pressure (10–12 bar) is necessary. Although some examples of gradient elution by CEC have been reported, with the common used instrumentation, this experimental mode is a bit difficult .…”

Nano-liquid chromatography (nano-LC) and CEC are microfluidic techniques mainly used for analytical purposes. They have been applied to the separation and analysis of a large number of compounds, e.g., peptides, proteins, drugs, enantiomers, antibiotics, pesticides, nutraceutical, etc. Analytes separation is carried out into capillaries containing selected stationary phase. The mobile phase is moved either by a pump (nano-LC) or by an EOF, respectively. The two tools can offer some advantages over conventional techniques, e.g., high selectivity, separation efficiency, resolution, short analysis time and consumption of low volumes of mobile phase. Flow rates in the range 50-800 nL/min are usually applied. The low flow rate reduces the chromatographic dilution increasing the mass sensitivity. Special attention must be paid in avoiding peak dispersion selecting the appropriate detector, injector and tube connection. Finally due to the low flow rate these microfluidic techniques can be easily coupled with mass spectrometry.

“…Much focus has been on finding efficient methodologies for the separation of such species from various environmental and biological matrixes. Also CEC‐MS studies have been developed for the analysis of PAHs, and four differing monolithic materials have been employed: silica , sol‐gel photopolymerization‐based methacryl‐oxypropyl‐trimethoxysilane (MPTMS) , hexylacrylate , and poly(stearylmethacrylate– divinylbenzene) (poly(SMA‐DVB)) monoliths. Since ionization with ESI for nonpolar PAHs is inefficient, API techniques have been utilized in these studies.…”

Here, we have reviewed separation studies utilizing monolithic capillary columns for separation of compounds preceding MS analysis. The review is divided in two parts according to the used separation method, namely CEC and capillary LC (cLC). Based on our overview, monolithic CEC-MS technique have been more focused on the syntheses of highly specialized and selective separation phase materials for fast and efficient separation of specific types of analytes. In contrast, monolithic cLC-MS is more widely used and is often employed, for instance, in the analysis of oligonucleotides, metabolites, and peptides and proteins in proteomic studies. While poly(styrene-divinylbenzene)-based and silica-based monolithic capillaries found their place in proteomic analyses, the other laboratory-synthesized monoliths still wait for their wider utilization in routine analyses. The development of new monolithic materials will most likely continue due to the demand of more efficient and rapid separation of increasingly complex samples.

“…Although there are no principal restrictions to interface CEC to APCI‐MS, only few information is available on the combination of these techniques. This is possibly because no commercial APCI interfaces are available for CEC and the difficulty in combining a packed capillary column to MS interface because of the poor reproducibility in the fabrication of the frit inside the capillary .

As a typical miniaturized analytical technique, CEC has attracted much attention because of its low sample and solvent consumption, high efficiency, high selectivity, high resolution, and fast speed. In this review, we mainly cover the development of capillary columns and detection techniques in the CEC since 2009. Herein, three types of capillary columns, namely, open-tubular capillary columns, monolithic columns and packed columns, and several types of detectors are reviewed in detail. Moreover, a 2D separation system based on CEC is also reported.
