 The Analytical Division of the Royal Australian Chemical Institute (RACI) held its 14th biennial symposium on analytical chemistry (14AC) in Adelaide, South Australia on 5–9 July 1997 [1]. The theme, "A broader view of the world" was an explicit invitation from the organisers to analysts to "take time away from their laboratories and consider how their work affects the world . . . A major challenge to chemists is to redefine their role in industry, education and the community and face, head-on, the demands brought about by free trade, economic rationalism and the environment." Part of this challenge, as reflected in invited plenary and keynote speakers as well as the cut and thrust of debate on the conference floor, is to address the important role of chemical measurement and confidence in the domestic and international systems of measurement.  相似文献

Conclusions Today Analytical Chemistry requires a broader definition than that concerned with its classical concept, objectives and methodology. The new concept of sample as a condensation of information of analytical interest has to be considered, as well as the increasing amount of instrumentation and metrology (physics) and data processing (applied mathematics; chemometrics) which are part of the present holistic definition of the subject. This is because the actual goals and constantly growing new objectives which today's Analytical Chemistry has to face and accomplish, are bound to a preliminary, strategic overview of the analytical problem (which often means much more than a simple sample). This problem has to be solved by the sensible, tactical application of the most suitable analytical method(s), worked out by Analytical Chemistry, the mother science of its instrument, chemical analysis.  相似文献

Conclusion The definition of Analytical Chemistry given above reflects not only the place, importance, structure and functions of this science today but also the trends in its evolution. Its nearest perspective are the rise of analytical knowledge to the higher levels in the hierarchy of the system of chemistry, the creation of new analytical methods for study of the composition, structure and dynamics of ever more highly organized chemical objects up to living reactors.  相似文献

Conclusion Although this multidisciplinary branch of science is growing rapidly today, yet two main points remain unchanged. On the one hand, it is analytical in essence; on the other, the information which it aims to acquire is chemical in nature, i.e. within the domain of chemistry. Accordingly it seems pertinent to reserve the term Analytical Chemistry for it. Other terms like analytical physics and chemical characterization are one-sided, with the aim or essence missing. The same is true of analytics and analytical science. Moreover, they should, literally speaking, include analytic geometry, analytical mechanics and so on.  相似文献

Benserazide (D, L-serine-2-[2,3,4-(trihydroxyphenyl)methyl]hydrazide) is one of aroma- tic L-amino acid decarboxylase inhibitors, and used with levodopa for treatment of Parkinson’s disease1. Hence, determination of benserazide is an indispensable program. Recently, chromatography2, spectrophotometry3,4 and capillary electrophoresis5 have been used for the determination of benserazide. However, these methods are low sensitive and inconvenient. In order to search new method for detecting ben…  相似文献

Advances in instrumentation and technology now provide the ability to perform many quantitative determinations in the field. Additionally, the potential for sample degradation and analyte decomposition make it necessary to determine certain analytes (e.g., dissolved oxygen) in the field when conducting environmental analyses. Unfortunately, field environmental—analytical chemistry is not a substantial portion of the analytical chemistry curriculum at many institutions. Students in lower-level analytical chemistry courses are often non-chemistry science majors, particularly at institutions with small chemistry departments. We report here on an experiment in which field environmental-analytical chemistry is introduced in the quantitative analysis laboratory. In the context of a water quality assessment of a local river, students determine temperature, pH, ORP, nitrate nitrogen, and ammonia nitrogen at several points in the river. The experimental objective is to determine the potential effects local agricultural practices and treated wastewater discharge may be having on the water composition. The pedagogical objective is to expose these students to the difficulties involved in making analytical determinations in unfamiliar and/or disruptive settings.  相似文献

The research for the new algorithm is in the forward position and an issue of general interest in chemometrics all along.A novel chemometrics method,Chemical Ant Colony Algorithm,has first been developed.In this paper,the basic principle,theevaluation function,and the parameter choice were discussed.This method has been successfully applied to the fitting of nonlinear multivariate function and the optimization of test conditions in chrome-azure-S-Al spctrophotometric system.The sum of residual square of the results is 0.0009,which has reached a good convergence result.  相似文献
