Advances in Chemical Analysis Procedures (Part I)

  • Type: Book
  • -
  • Published: 2020-12-02
  • -
  • Publisher: MDPI

The availability (and the development) of innovative approaches to quantitative analyses and the data processing are often mandatory to deeply characterize a sample and to correctly highlight the analytical target. These objectives are carried out either by simply improving a single aspect of the analytical protocol or by developing a synergy of steps (from extraction to instrumental configuration to chemometric approaches) to obtain the maximum analytical information sought. Examples are innovative extraction protocols (also following the recent guidelines on green analytical chemistry) or new materials for the selective extraction of target compounds, multi-analytes screening methods, and ...

Advances in Chemical Analysis Procedures (Part II)

  • Type: Book
  • -
  • Published: 2021-01-20

  • Publisher: MDPI

In the field of Analytical Chemistry and, in particular, whenever a quali-quantitative analysis is required, until a few years ago, reference was made exclusively to instrumental methods (more or less hyphenated) which, once validated, were able to provide the answers to the questions present, even if only in a limited way to analytical targets. Nowadays, the landscape has become considerably complicated (natural adulterants, assessment of geographical origin, sophistication, need for non-destructive analysis, search for often unknown compounds), and new procedures for processing data have greatly increased the potential of analyses that are conducted (even routinely) in the laboratory. In t...

Analytical Microextraction Techniques

Sample treatment has been the focus of intensive research in the last 20 years since it still remains a bottleneck in precise analytical procedures. The low concentration of the target analytes, the large amount of potential interfering agents and the incompatibility of the sample matrix with the instrumental techniques are the main reasons for these bottlenecks. In most of these methods, sample treatment is an unavoidable step and it has a clear influence on the quality (sensitivity, selectivity, and accuracy) of the final analytical results. While the usefulness of microextraction techniques has been established, their complete acceptance in analytical laboratories (including official meth...

  • Published: 2019-07-11
  • -
  • Publisher: MDPI

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive...

Forensic Analytical Methods

Forensic analysis relates to the development of analytical methods from laboratory applications to in-field and in situ applications to resolve criminal cases. There has been a rapid expansion in the past few years in this area, which has led to an increase in the output of literature. This is the first book that brings together the understanding of the analytical techniques and how these influence the outcome of a forensic investigation. Starting with a brief introduction of the chemical analysis for forensic application, some forensic sampling and sample preparation, the book then describes techniques used in forensic chemical sensing in order to solve crimes. The techniques describe current forensic science practices in analytical chemistry and specifically the development of portable detectors to guide the authorities in the field. The book provides an excellent combination of current issues in forensic analytical methods for the graduates and professionals. It will cover the essential principles for students and directly relate the techniques to applications in real situations.

Fabric Phase Sorptive Extraction

  • Publisher: Elsevier

Fabric Phase Sorptive Extraction: Principles, Applications and Potentials is the first book to cover this new sample preparation technique. Sample preparation remains a matter of great concern and interest among academics, researchers and scientists as it is undoubtedly a major source of error and the most time-consuming step in the analytical/bioanalytical workflow, and the lack of harmonization among different sample preparation technologies inherently creates disparity in the data quality. To minimize the impact of sample preparation, FPSE combines the extraction mechanisms of two major sample preparation techniques-solid phase extraction (governed by exhaustive extraction) and solid phas...
