The Encyclopedia of Separation Science is the most comprehensive resource available on the theory, techniques, and applications of separation science. The work presents information on three levels. The first volume contains Level 1, which provides a broad overview of the theory of the 12 main categories of separation techniques.   The components can then be collected separately, assuming adequate separation was achieved, in order of increasing polarity. This method of chromatography is not unique to liquid-solid column chromatography and is often used when performing High Performance Liquid Chromatography (HPLC). Liquid chromatography can further be 13 divided into ion exchange, separations based on size, and even extended to gel based electrophoretic techniques. This book will provide a basic introduction to 15 different types of liquid and gas chromatography. The relationship between each 16 type of chromatography is illustrated in Figure Chromatography was first devised in Russia by the Italian-born scientist Mikhail Tsvet in He developed the technique, he coined chromatography, in the first decade of the 20th century, primarily for the separation of plant pigments such as chlorophyll, carotenes, and these components separate in bands of different colors (green, orange, and yellow, respectively) they.

After surface modification with octadecyl trichlorosilane, the obtained monodisperse C silica microspheres with an average diameter of μm were applied to ultra performance liquid chromatography (UPLC) separation of fullerenes. Simultaneous separation and identification of perchlorinated polycyclic aromatic hydrocarbons (PCPAHs) and fullerenes is of practical interest due to the growth mechanism of fullerenes involved with PCPAHs.

Fullerenes, mainly C 60 and C 70, were Soxhlet extracted from collected soot with chlorobenzene, by modified procedure yielding % of the extract. Chlorobenzene fullerenes extract was then separated on an active alumina column, modifying the existing methods, by elution with hexane and xylene/hexanes mixtures in determined ratios and orders.

The assignments from chromatography and NMR experiments were supported by the analysis of the UV–vis absorption spectrum of the IC 70 BA fractions. It is widely known that the UV–vis spectrum of fullerene derivatives are highly correlated to their conjugated structures [].Therefore, comparison of the UV–vis spectrum of each fraction with known C 70 bisadducts, for example the known 2 o. Three copper-phthalocyanine stationary phases (Cu-PCS) were evaluated for fullerenes separation with microcolumn liquid chromatography. These phases offer two dominant interactions between fullerenes and the bonded moiety, solvophobic interaction, and π-π interaction.

Often liquid-liquid extraction (LLE) is used to extract individual C 60 molecules from aqueous solutions of fullerene aggregates (nC 60) into toluene for LC–UV or LC–MS quantification [16, 31]. Solid-phase extraction (SPE) is a common method for extracting analytes from urine [ 32 – 34 ] and has been used to extract nC 60 from larger.
