Laborpraxis Volume 4: Analytical Methods

The four-volume standard work for fundamental practical work in the chemical-pharmaceutical laboratory with a focus on synthesis methods, chromatography and spectroscopy is now available in the 6th, completely revised edition. It serves as a broad teaching aid for career starters and as a reference work for experienced specialists with clearly presented theoretical principles and concrete, tried and tested application ideas.

The theoretical basics for each chapter are clearly legible and support the understanding of practical work and device functions. For each chapter there are references to more detailed and further literature. Occupational safety and hygiene as well as the twelve principles of sustainable chemistry are taken into account in addition to the corresponding chapters. The practical principles mentioned in the book are based on conditions in the chemical-pharmaceutical industry in Switzerland. They are used in the entire German-speaking area, also in related fields such as biochemical, clinical, materials science or university laboratories.

Laboratory practice is suitable for use in basic and advanced training for specialist staff. The content corresponds to the current requirements of the education ordinance and the education plan for occupation L.Aborantin / laboratory assistant with federal certificate of proficiency (EFZ), which were decreed by the State Secretariat for Education, Research and Innovation (SERI) in Bern. This provides the learners with a good basis for preparing for the qualification procedure (QV); Experts base their personal preparatory work and their professional assessments on this book.

Volume 1 and Volume 2 deal in detail with the basics of laboratory work and selected measurement techniques. Volume 3 focuses on preparative and analytical separation methods, Volume 4 on wet chemical and spectroscopic analysis methods. Both conventional methods and the most modern techniques are mentioned. The focus on consistently valid principles also allows us to understand new, unmentioned technological trends and to reflect on daily work in the chemical-pharmaceutical laboratory.
