Analytical Chemistry in Modern Society: What we can Expect

Analytical chemistry today contributes many analytical techniques which are required in industry, environmental control, medical laboratories and other areas of society. However, increased portability and miniaturization has the potential to enable us to solve new problems such as the analysis of new matrices including the possibility to analyse even cellular compartments. In this development process it is also being attempted to produce instruments and techniques which can be used by non-specialists. The integration, in a recent future, of microanalytical systems into our water taps permitting to control the presence of contaminants or microanalytical systems to control our health profile are some examples of the future contribution of analytical chemistry to society which probably will change our life.

课程思政背景下分析化学辩证元素探索及教学实践

In the university, analytical chemistry is an important basic course for junior college students. There is a variety of dialectical views, rules, and relationships of materialism in analytical chemistry. Fully excavating these dialectical elements and infiltrating them into the classroom teaching process is necessary. This will not only help students deeply understand the subject knowledge, but also cultivate their dialectical thinking mode, establish the correct worldview and scientific methodology. This is conducive to the same resonance frequency between knowledge education and thinking education, and fits the current course ideological and political education. In the present paper, combining many years of teaching practice, the author briefly explains the integration of dialectical elements in analytical chemistry with the corresponding teaching content.

Evading the Illusions: Identification of False Peaks in Micro-Raman Spectroscopy and Guidelines for Scientific Best Practice

Micro-Raman spectroscopy is an important analytical tool in a large variety of science disciplines. The technique is suitable for both identification of chemical bonds and studying more detailed phenomena like molecular interactions, material strain, crystallinity, defects, and bond formations. Raman scattering has one major weakness however: it is a very low probability process. The weak signals require very sensitive detection systems, which leads to a high probability of picking up signals from origins other than the sample. This complicates the analysis of the results and increases the risk of misinterpreting data. This work provides an overview of the sources of spurious signals occurring in Raman spectra, including photoluminescence, cosmic rays, stray light, artefacts caused by spectrometer components, and signals from other compounds in or surrounding the sample. The origins of these false Raman peaks are explained and means to identify and counteract them are provided.     

Some Latin American experiences concerning teaching of chemical metrology

In this paper, 15 years of the experiences acquired concerning the teaching of chemical metrology in Latin America are presented. These include postgraduate and undergraduate activities developed in eight countries. The combination of theoretic and practical activities and the sequence of learning from metrological, statistical, and chemometrical backgrounds up to practical activities in personal computers are basic and motivate the learning process. Care is taken to promote the metrological approach and thinking in analytical chemistry. The learning of computing techniques plays an important role, combining graphic and numerical techniques for data analysis. The role of examples during the teaching process is analyzed and recognized. The introduction of a general model of errors permits one to approach different topics on a metrological basis. The metrological approach of uncertainty based on the theory of errors permits one to develop the topic. Undergraduate students acquire a basic metrological knowledge and other experiences are also presented. Recommendations for undergraduate and postgraduate programs are pointed out.

In general, the teaching reforms have shown that the educational reform can improve self-learning abilities and cultivate innovation ability of students, and thereby improve the teaching quality of agricultural inorganic and analytical chemistry effectively.     

The Teaching/Learning Process in Analytical Chemistry

Before teaching a course, the instructor must identify what she or he intends for the students to learn. For most analytical chemistry instructors, this usually involves an assessment of what methods and techniques to include and at what depth to cover them. There are many other skills, though, that will be important to students for their future success. Most college classes in analytical chemistry are taught in a lecture format. Techniques that can be used to improve the learning that can occur during a lecture are described. An alternative to lecturing is the use of cooperative learning. Cooperative learning offers the potential to develop skills such as teamwork, communication, and problem-solving that are more difficult to impart in a lecture format. The laboratory component of analytical chemistry courses is often an underutilized learning resource. More often than not, the lab is used to demonstrate fundamental wet and instrumental analysis techniques and develop rudimentary laboratory skills. The analytical lab should also be used to develop meaningful problem-solving skills and to demonstrate and have students participate in the entire analytical process. Ways of enhancing the analytical laboratory to include more global skills that are important to career success are described.Received January 12, 2003; accepted March 7, 2003 Published online July 16, 2003

Design and development of computer-aided chemical systems: representation and balance of inorganic chemical reactions

A model for the tracking of inorganic chemical reactions is proposed. Designed to acquire, process, and solve a great number of inorganic reactions, this model will hopefully contribute to the development of powerful computer-aided chemistry teaching systems for use within or without the environment of a virtual laboratory. Using full representation of an inorganic reaction to allow the extraction of chemical knowledge, incomplete reactions (where species are absent) may be completed by adding the necessary species, and reactions may be solved and balanced. Various types of reaction are classified, and a layer-based model is defined for the solution of different reaction types, establishing the basis for the construction of a system which, based on a wide set of production rules, is capable of solving an incomplete inorganic chemical reaction.     

Probiotics Production: An Interesting Example for the Undergraduate Analytical Chemistry Laboratory

An analytical chemistry laboratory experiment for undergraduates that combines traditional analytical chemistry techniques with the interdisciplinary field of biotechnology is presented. It involves a process in which the combination of a yeast (Schizosacaromyces pombe) and a bacteria (Acetobacter xylimun), usually named Kombucha, in a very simple culture of commercial black tea and glucose produces metabolites that are sampled and quantified by students. Students determine the biomass and quantify the production of several organic acids, and the consumption of glucose. This is an interdisciplinary project where students apply many tools of the general analytical process and combine results obtained by all the participating students to learn the characteristics of a biotechnological process. Overall, the system discussed is easy to implement because the selected micro-organisms are not pathogenic, are safe and easy to manipulate, and are resistant to contamination.
