A new method has been developed for preparing monolithic materials by polymerisation of the oil-in-water (O/W) emulsions with nonion-surfactant (Pluronic F68). Morphology of monolithic materials is studied by scanning electron microscopy. The properties of the column are investigated, and the column exhibits the ability of low backpressure and fast analysis. Using this monolithic column, on-lin...

In this work, a new oligomer matrix-assisted dispersion (OMAD) method for the preparation of homogeneous dispersion of multi-walled carbon nanotubes (MWNTs) incorporated monolithic column was developed. Oligomers matrix as a scaffold could allow MWNTs to entangle with it instead of self-aggregation, so the MWNTs remain in the polymer network followed by in situ self-solidification. The OMAD met...

The monolithic integration of a high sensitivity detector with a gas chromatography (GC) separation column creates many potential advantages over the discrete components of a traditional chromatography system. In miniaturized high-speed GC systems, component interconnections can cause crucial errors and loss of fidelity during detection and analysis. A monolithically integrated device would eli...

A capillary electrochromatography (CEC) monolithic column with zwitterionic stationary phases was prepared by in situ polymerization of butyl methacrylate, ethylene dimethacrylate, methacrylic acid, and 2-(dimethyl amino) ethyl methacrylate in the presence of porogens. The stationary phases have zwitterionic functional groups, that is, both tertiary amine and acrylic acid groups, so the ionizat...

The monolithic column is a single piece of a continuous rigid porous polymer that possesses an interconnected skeletal structure and contains pores. According to their components, monolithic materials can be divided into organic polymer-based monoliths and inorganic silica-based monoliths. This review focuses on silica-based monolith with special emphasis on the preparation. Moreover, this revi...

The column is the main component for chromatographic separation. Nowadays, monolithic columns are graining more popularity in field of separation media liquid chromatography. monolith possess great potential as compared to conventional packed terms preparing complex mixtures. These provide various properties like higher permeability, high-efficiency fast separations, high flow rate with lower b...

A capacitively-coupled contactless conductivity detector (C4D) has been utilised as an on-capillary detector within a capillary ion chromatograph, incorporating a reversed-phase monolithic silica capillary column semi-permanently modified with a suitable ionic surfactant. The monolithic capillary column (150 x 0.1 mm i.d.) was modified using sodium dioctyl sulfosuccinate (DOSS), an anionic surf...

A method is developed toward high sequence coverage of proteins isolated from human breast cancer MCF10 cell lines using a 2-D liquid separations. Monolithic-capillary columns prepared by copolymerizing styrene with divinylbenzene are used to achieve high-resolution separation of peptides from protein digests. This separation is performed with minimal sample preparation directly from the 2-D li...

AbstractThe occurrence of deoxynivalenol (DON) in retail foods in Tehran (Iran) was determined using high-performance liquid chromatography technique and immunoaffinity column as the clean-up step. A method was validated for analysis of DON in rice, bread, puffed corn snack and wheat flour. The average recoveries and precision (RSD) for DON in different foods ranged 84.2-93.1% and 2.9-12.0%, re...
