MINIATURIZED TECHNIQUES OF PREPARATION OF LIQUID SAMPLES FOR ENVIRONMENTAL ANALYSES. CTA Vol 26 (2) 68-87 (2005).
Abstract: This article summarizes recent developments in the field of miniaturized preparation of extracts and liquid samples for analysis of organic pollutants on the basis of selected examples in which the final determination is made using liquid chromatography (LC), gas chromatography (GC) or capillary electrophoresis (CE), in combination with conventional detectors. Special attention is given to those miniature techniques that have proven validity for the analysis of real samples. It also presents examples of fields close to the environment, such as the biomedical and food analysis, evaluating in all cases the main advantages and limitations in the techniques reviewed. |

Abstract: This paper discusses the advantages and limitations of metabolomics in the application of various chromatographic techniques and their couplings to mass spectrometry. It also addresses the need to define and unify the hitherto vague terminology used in metabolomics, and proposed a simple nomenclature where the terms Metabolite target analysis, Metabolite / Metabolic profiling, Metabolic fingerprinting, Metabolomics and Systems Biology are used to describe studies with different purposes within of metabolomics. Finally, some examples of application of the study of metabolites in plants and food as well as various applications in the field of toxicology and medicine, are described. It also includes a list of websites of interest related to metabolomics. |
