Due to a combination of the modified technique for sensor analysis of composite gas mixture with unique properties of the gas-sensitive point-contact matrix, a complex dynamic of interaction between sensitive matter and volatile compounds of exhaled air has been observed. This interaction is characterized by longer adsorption times. This behavior was not observed in our previous work on breath analysis where fihn samples were used [11]. 

Finally we would like to express our gratitude to all the authors for sharing their expertise in the field of electrochemical sensors analysis. The highest quality research presented here will do much to promote real sample analysis with electrochemical (bio)sensors. 

This book on Electrochemical (Bio)Sensor Analysis, edited by S. Alegret and A. Merko< i, is an additional step to advance the field of rapid analysis. It presents advanced sensor developments as well as practical applications of electrochemical (bio)sensors in various fields in a single source. The book contains 38 chapters grouped into seven sections (a) Potentiometric sensors, (b) Yoltammetric (bio)sensors, (c) Gas sensors, (d) Enzyme based sensors, (e) Affinity biosensors, (f) Thick and thin film biosensors, and (g) Novel trends. This interdisciplinary book has contributions from well-known specialists in the field and will be a useful resource for professionals with an interest in the application of electrochemical (bio)sensors. 

There is a continuing demand for the application of electrochemical sensors with a good quality/cost performance not only in comparison to sensors based on other transducer mechanisms but also to some standard analytical methods. Electrochemical Sensor Analysis (ECSA) presents novel theoretical considerations along with detailed applications of electrochemical (bio)sensors. The combination of both theoretical and practical aspects provides a comprehensive forum that integrates interdisciplinary research and development, presenting the most recent advances in applications in various important areas related to everyday life. Additionally ECSA reflects that electrochemical sensor analysis is already a well established research and applied area of analytical chemistry. 

Our main objective was to prepare a useful reference source for all those involved in the research, teaching, study, and practice of electrochemical (bio)sensor analysis for environmental, clinical and industrial analysis. It covers the entire field of electrochemical (bio)sensor designs and characterisations and encompasses all subjects relevant to their application in real clinical, environment, food and industry related samples as well as for safety and security. The contributors work in a wide diversity of technological and scientific fields. 

E. coli as well as Salmonella enterica bind to mannose. This limitation may be overcome using cross-reactive sensor analysis [56]. Thus, the binding to a variety of different analytes is checked in parallel. By comparison with known data, the detection and determination of single or multiple pathogens, even within complex mixtures, should be possible in the near future. The underlying principle is the basis for the olfactory sense in most animals.

Laboratory measurements use special instmments for highly accurate analysis and field instmments are used for a quick assessment of conditions. Some instmments are attached to workers (personal samplers or dosimeters) to monitor exposures. Some of these dosimeters determine directly if an exposure exceeds the 8-hr TWA. Arrays of sensors, analysis equipment, and alarm systems are managed by computers to provide continuous monitoring for releases. They warn people by triggering evacuation or corrective procedures for equipment. Many of the instmments require regularly scheduled calibration to assure accurate results. There are a wide range of collection procedures and devices. This discussion is a limited review of collection and analysis equipment.
