A brief account is provided on the history of chemometrics in Argentina, from the creation of the Argentinean Association of Analytical Chemists inwhich created the opportunity of joining efforts for a more rational development of the discipline in the country, to the present days, with a variety of groups conducting research in several different aspects of chemometrics.

The National University of San Luis held the most active research group on analytical chemistry, and it is thus understandable that the first impulse for the creation of the association cheommetrie from them. It was a long-sought aim of various members of several research groups, which were rather dispersed across the country and with little communication among them.

The purpose of the AAQA was to organize scientific meetings in such a way that the communication gap was closed as much as possible, to promote the development of Analytical Chemistry throughout the country, and to encourage young people to join the Association and pursue the discipline.

That initial effort proved to be highly successful. Today the AAQA has hundreds of members, has promoted and financed post-graduate courses in different universities, and has already organized six national scientific meetings; the seventh one was held at the city of Mendoza in October http: The AAQA meetings are now regularly organized every two years in different Argentinean cities, with a continuously increasing number of participants and work presentations, and chemometrir the contribution of distinguished foreign researchers as lecturers, organization of round tables on various subjects education, connection with industry, etc.

A particularly important aspect is that every AAQA chemometris brings several foreign ansries speakers, whose subject are distributed among the main areas of analytical chemistry research, i. One particular event triggered by the foundation of the AAQA concerns chemometrics.

At the founding meeting in San Luis inresearchers working in different aspects of chemometrics, who did not know each other personally, found themselves in the same place, talking about common issues.

After this event, a series of other, more causally connected facts occurred. The chemometricians decided to join efforts in promoting the discipline, by giving courses both personal and electronic in different universities, to receive young researchers with chemometric interests in their laboratories, and to invite well-known chemometricians from abroad to give courses, or lectures at the AAQA congresses, among other actions.

As a result of the particularly fortuitous occasion intherefore, the current situation of chemometrics in Argentina is significantly better than before. It is, however, far from being ideal, but considerable progress has been made. The three main chemkmetrie areas of interest are now being pursued in several laboratories: In what follows some representative works in these areas will be mentioned, including the cities in which the researchers work.

Design of experiments and optimization. The need of rationally designing experiments in order to assess the relevant factors affecting a given response, and the importance of optimizing an objective response using statistical techniques is now fully appreciated by most members of the chemistry community in Argentina. Some groups Santa Fe dhemometrie Buenos Aires devote efforts to develop new screening tools, based on genetic algorithms applied to Plackett-Burman designs, 1,2 or optimization methodologies based on the use of artificial neural networks.

Related techniques based on artificial neural networks have been applied to study patients in neutron capture therapy 19 or sources of environmental pollution Buenos Aires. In the area of multivariate calibration, complex sample analysis using first-order spectroscopic methods coupled to partial least-squares regression PLS and other variants has been the interest of several groups.

Second- and higher-order calibration, i. The need of processing and interpreting the huge amount of data provided by these instruments will certainly trigger increasing developments and awareness of the possibilities offered by them.

New developments in the estimation of figures of merit have been recently published Rosario.

Somewhat ironically, the San Luis researchers who organized the founding meeting for the AAQA have wndries research interests in two areas which are in less need of chemometric assistance: It is a nice example of serendipity, because the unplanned first brick laid by the San Luis group in gave rise to the growing construction of the chemometric discipline of today.

A long way is expecting us in the future. Some proposals for increasing the strength of chemometrics in Argentina follow, partly by consideration of the short story told above, partly by looking at what other countries have done in the past, especially Brazil. The first advice for scientific policy makers of our country is to avoid randomness to be the cause of the development of any discipline, including chemometrics.

We need planning, and by planning I mean several political actions that should be taken by authorities: Another proposal aimed at improving the development of chemometrics in Argentina wndries the promotion of international contacts.

Cooperation projects with major universities and research centers of USA and Europe should be stimulated, young people should be supported if they intend to learn advanced chemometrics in the world’s most prestigious laboratories. Experts from those centers should be invited to Argentina to give lectures, courses, seminars, etc.

The assistance of ca. Lectures and courses from Brazilian chemometricians and researchers from USA, Europe and Argentina during that particular week were possible in an atmosphere of both friendship and scientific progress. Finally, regional cooperation among South American countries should be encouraged, with a two-fold purpose: Political decisions and real actions in this field are needed, as part of a higher aim: Acta, Chemometrics25Chemometrics17Chemometrics23Acta A, B, Drug2September 20, Published online: Alejandro Olivieri was born in Rosario, Argentina, on July 28, He has published about scientific papers in international journals, several books and book chapters and supervised nine PhD Theses.
