In the recent past quantitative chemical analysis textbook writers included selected experiments to complete and complement the text and thus give instructors a choice to select the experiments to be performed by students in quantitative analysis course. On the other hand, this is not so for courses in instrumental analysis which is a sequential course to quantitative analysis. This is, perhaps, due to the numerous instrumental techniques that have been developed over the years for chemical analysis. In its stead, textbooks on experiments in instrumental analysis are common, and these are as diversified as the topics covered in lecture courses. Most of the experimental topics covered, especially, in quantitative analysis, lean heavily on determination of materials or compounds of inorganic chemistry origin. This seems to be the tradition with only a few exceptions. However, recently, textbooks on quantitative analysis have emerged and continue to emerge, without any experimental section. This is not quite surprising though, since many instructors nowadays, tend to design their own experiments to suit and complement their lecture materials. On the other hand, the trend in the production of books on instrumental analysis experiments has remained the same. The objective of this book is therefore two fold. One is to design a reasonably comprehensive laboratory text that embodies both areas of analytical chemistry. The other is to shy away from the tradition of making quantitative analysis experiments lean too heavily on inorganic materials. To this end, several topics ranging from inorganic to organic materials are included in this laboratory text book. A new element is also introduced inthis book. That is, students are exposed throughout the book to the analysis of compounds of pharmaceutical relevance.

This thesis describes novel substrate embedded physical sensors that can be used to monitor different types of cell-based assays non-invasively and label-free. The sensors described provide integrative information of the cells under study with an adaptable time resolution (ranging from milliseconds to days). This information about the dynamic cell response to chemical, physical or biological stimuli defines a new paradigm in fundamental biomedical research. The author, Maximilian Oberleitner, describes approaches in which the cells are directly grown on different sensor surfaces (gold-film electrodes, shear wave resonators or dye-doped polymer films). This approach, with the reacting cells in particularly close proximity and contact with the sensor surface, is key to a remarkable sensitivity, opening the way for a variety of new applications. This thesis not only introduces the fundamentals of each approach, but it also describes in great detail the design principles and elucidates the boundary conditions of the new sensors.

This book focuses on scientific and technological aspects of groundwater-resources assessment and surveillance. It describes relevant risks and investigates selected techniques for the monitoring and mitigation of the individuated threats to groundwater quality.

Furthermore, the role played by geochemical techniques, the potential of environmental isotopes and the support provided by physical modelling are highlighted. The chapters guide the reader through various viewpoints, according to the diverse disciplines involved, without aiming to be exhaustive, but instead picking representative topics for their relevance in the context of groundwater protection and control. This book will be of interest to advanced students, researchers, policy-makers and stakeholders at various levels.
