The variety of chemical modifications of the surface of silica and its modified forms cause these materials to find a consistently wider scope of application. In the publication, the characteristics of silica, silica gel, aerogel and xerogel are presented. The obtainment, application and properties of these materials are discussed. Methods of chemical modifications of surface structures with the use of different chemical compounds are presented. Special attention is turned to the behavior of silica and its modified form during the adsorption process. The main applications of silica and its different forms in analytical chemistry are also discussed.

“…Mass spectrometry (MS) coupled to HPLC is a powerful technique with many applications within the field of analytical toxicology [10,11], and it has also been used for the analysis of catecholamine and other NT in several biological fluids [6,[12][13][14][15]. Nevertheless, most of these methods have several inconveniences, such as the necessity of previously treating the sample or the chromatographic separation by ion pair reagents, which typically hinder MS detection.…”

“…HPLC with electrochemical detection is the most commonly used method for quantitative determination of biogenic amines and metabolites in tissue, plasma and urine (Cheng and Kuo, 1995;Chi et al, 1999;Davis et al, 1981;Gilinsky et al, 2001;Machida et al, 2006;Patel et al, 2005;Sabbioni et al, 2004;Sastre et al, 2004;Unceta et al, 2001). Another informative, but less used technique, for bioanalyte monitoring in tissue is capillary electrophoresis (CE) (Dillon and Sears, 1998;Markuszewski et al, 2003;Paxon et al, 2005;Qurishi et al, 2002;Shou et al, 2004).…”

Capillary electrophoresis with end-column amperometric detection (CE-EC) was used to determine the regional distribution of norepinephrine (NE) in the hearts of sympathetically innervated (control) and chemically sympathectomized rats. Key features of the method are (i) the sample preparation and clean-up step that involved the application of off-line solid phase extraction (SPE) with a 95% NE recovery and (ii) the use of a diamond microelectrode for detection. NE was quantified in the left and right ventricle, the ventricular septum, and the left and right atrium. The NE concentration in the atria was three to five times higher than in the ventricles and ventricular septum of control rats. Basal NE levels in the left and right ventricle and the ventricular septum were reduced to below the detection limit (0.034 microg/g tissue) in tissues treated with the neurotoxin, 6-hydroxydopamine (6-OHDA), while only a moderate reduction was observed in the left and right atrium. Importantly, the diamond microelectrode provided low and stable background current and low peak-to-peak noise
