Working Group Chemometrics & Quality Assurance

Tasks & Objectives

The Working Group Chemometrics & Quality Assurance was founded in 1991 under the name chemometrics & Laboratory Data Processing working group by merging the chemometrics Working Group of the Chemical Society of the GDR and the GDCh Laboratory Automation and Data Processing Working Group. In line with the focus of these two groups, the working group of the GDCh Division of Analytical Chemistry aims to combine the acquisition of data in the laboratory with its statistical evaluation, plausibility checks and corresponding quality assurance as good analytical practice. This is why it is particularly aimed at analysts who acquire a lot of data in the laboratory in stationary analysis and in dynamic processes and who also process it further. The working group is also interested in the application of uni- and multivariate methods of data analysis, methods for classification and pattern recognition, and the Management of "big data" and its integration into the analytical process.

The working group is present at national and international Conferences or takes the lead in organizing them. The working group also participates successfully in the analytica conference. Last but not least, aspects of the working group are regularly reflected in presentations at ANAKON . Due to the constantly increasing number and complexity of chemometrics methods, the working group has set itself the goal of developing guidelines for the practical use of chemometric methods.

The working group

promotes interdisciplinary collaboration between chemometricians in all disciplines of analytical chemistry and related fields
analyzes and observes trends and new processes
supports method development and application
is the contact person for national and international organizations
is committed to and at international conferences and Conferences
provides advice in the areas of data analysis, quality assurance and data management, and in the definition of terms and formulations
develops guidelines for the application of chemometric methods
organizes seminars for training and vocational training.
