Quo vadis, Analytical Chemistry?
Analytical and Bioanalytical Chemistry, 2016Co-Authors: Miguel ValcárcelAbstract:This paper presents an open, personal, fresh approach to the future of Analytical Chemistry in the context of the deep changes Science and Technology are anticipated to experience. Its main aim is to challenge young Analytical chemists because the future of our scientific discipline is in their hands. A description of not completely accurate overall conceptions of our discipline, both past and present, to be avoided is followed by a flexible, integral definition of Analytical Chemistry and its cornerstones (viz., aims and objectives, quality trade-offs, the third basic Analytical reference, the information hierarchy, social responsibility, independent research, transfer of knowledge and technology, interfaces to other scientific–technical disciplines, and well-oriented education). Obsolete paradigms, and more accurate general and specific that can be expected to provide the framework for our discipline in the coming years are described. Finally, the three possible responses of Analytical chemists to the proposed changes in our discipline are discussed.

Analytical Chemistry Today and Tomorrow
Analytical Chemistry, 2012Co-Authors: Miguel ValcárcelAbstract:Dealing with Analytical Chemistry in isolation is a gross error [1]. In fact, real advances in Science and Technology —rather than redundancies with a low added value on similar topics— occur at interfaces, which are boundaries, crossroads —rather than barriers— between scientific and technical disciplines mutually profiting from their particular approaches and synergistic effects. Figure 1 depicts various types of interfaces involving Analytical Chemistry.

A modern definition of Analytical Chemistry
TrAC Trends in Analytical Chemistry, 1997Co-Authors: Miguel ValcárcelAbstract:Abstract A definition of Analytical Chemistry is established from what it is and is bound to be. The definition is complemented by a description of the basic elements, fundamentals, key words, boundaries and evolution of Analytical Chemistry. Finally, an overview of global and specific trends in this discipline is provided.

Analytical Chemistry and quality
TrAC Trends in Analytical Chemistry, 1994Co-Authors: Miguel Valcárcel, Angel RíosAbstract:The word “quality” has been used systematically in the previous chapters of this book, devoted to the fundamentals of Analytical Chemistry, to refer to the degree of excellence of various Analytical objects, systems and events. These are some of the more meaningful examples: In the definition of Analytical Chemistry (Sect. 1.1), quality is an attribute of the information produced. Analytical information encompasses three quality levels, viz. ideal, referential and real (see Fig. 1.6). Quality as applied to information, traceability and the Analytical process, and as related to Analytical properties, is one of the key words of Analytical Chemistry (see Fig. 1.10). Analytical quality (viz. quality of CMPs and of results) is direct1y related to Analytical properties and their hierarchies (see Fig. 2.1). As shown in Box 3.15, standards contribute to quality of Analytical laboratories. The principal aim of method validation is to assure Analytical quality (see Sect. 4.6). Analytical properties and errors (false positives and false negatives) characterize the quality of the binary response in qualitative analysis (see Sects. 5.2.3 and 5.2.4). The Analytical properties of a quantitative response somehow dictate its quality (Sect. 6.2). As shown in Sect. 7.7, the Analytical problem is also related to quality.

Analytical Chemistry — today's definition and interpretation
Fresenius' Journal of Analytical Chemistry, 1992Co-Authors: Miguel ValcárcelAbstract:Analytical Chemistry is thus the science of chemical measurements. As such, it can and must help to solve social and R & D problems by resolving underlying Analytical problems. In so doing, this discipline must be placed in the scientific-technical context where it belongs and isolationist positions must be avoided. Today's and tomorrow's Analytical Chemistry does not begin at the laboratory door and ends at the printer or plotter. Research and development (R & D) strategies, existing Analytical methods and techniques and constructive education are the essential ingredients of Analytical Chemistry if it is to fulfil its generic informative objective veraciously, efficiently and rapidly with little human and economic expenditure.

History and Milestones of Green Analytical Chemistry
Green Chemistry and Sustainable Technology, 2019Co-Authors: Justyna Płotka-wasylka, Magdalena Fabjanowicz, Kaja Kalinowska, Jacek NamieśnikAbstract:Due to the increased environmental consciousness, Green Analytical Chemistry (GAC) is an important concept steadily gaining popularity, as its implementation facilitates the decrease the detrimental effect Analytical Chemistry methodologies may have on the environment. In this chapter, a brief overview of the history of Green Analytical Chemistry (GAC) and its milestone was given. Emphasis has been put on the beginnings of green Chemistry awareness and on the possibilities of increasing and evaluating the greenness of both currently used and designed Analytical Chemistry methodologies. In addition, the prospects of implementation of 12 principles of Green Analytical Chemistry have been briefly described.

Green and equitable Analytical Chemistry
Current Opinion in Green and Sustainable Chemistry, 2019Co-Authors: Renata Marcinkowska, Jacek Namieśnik, Marek TobiszewskiAbstract:Green Analytical Chemistry introduces the ideas of reduction of Analytical activities impact on the environment. However, to be more sustainable, Analytical Chemistry should include social aspects in greater manner. In this light ‘equitable’ Analytical procedures, which are easily available in terms of price and applicability by everyday user, are developed. These positive trends are observed as many procedures, based on commonly used for nonAnalytical purpose devices, are developed. Some examples of methods based on smartphones, scanners, 3D printers, or espresso machines are presented herein. With this contribution, we want to stress that green Analytical Chemistry is not tantamount to sustainable Analytical Chemistry as it does not include social equity factors.

Metrics for green Analytical Chemistry
Analytical Methods, 2016Co-Authors: Marek TobiszewskiAbstract:Green Analytical Chemistry, although not being a new concept, does not have a greenness metrics system. Green Chemistry metrics are not suitable for Analytical procedure assessment because they often refer to the mass of the product. Some efforts have been made to develop suitable metrics for Analytical Chemistry. Some are simple to use but do not cover all aspects of Analytical methods’ environmental impact. Others are more comprehensive but may be difficult to be applied. The Analytical reagents were not assessed but some clues about their greenness can be obtained from assessments from other branches of Chemistry. New reagents and solvents applied in Analytical Chemistry require their detailed assessment in terms of greenness. Environmental issues have to be taken into consideration during reagent and solvent selection, Analytical waste disposal practices, the energetic requirements of Analytical processes and the development or selection of Analytical procedures, and, for that reason, metrics systems are required.
