Organisms from all domains of life invest a substantial amount of energy for the introduction of RNA modifications into nearly all transcripts studied to date. Instrumental analysis of RNA can focus on the modified residues and reveal the function of these epitranscriptomic marks. Here, we will review recent advances and breakthroughs achieved by NMR spectroscopy, sequencing, and mass spectrometry of the epitranscriptome.

There is a high demand for easy, cheap, comparable, and robust methods for microplastic (MP) analysis, due to the ever-increasing public and scientific interest in (micro-) plastic pollution in the environment. Today, a multitude of methodologies for sampling, sample preparation, and analysis of MPs are in use. This feature article deals with the most prominent detection methods as well as with sampling strategies and sample preparation techniques. Special emphasis is on their benefits and challenges. Thus, spectroscopic methods, coupled with microscopy, require time-consuming sample preparation and extended measurement times, whereas thermo-analytical methods are faster but lack the ability to determine the size distribution in samples. To that effect, most of the described methods are applicable depending on the defined analytical question.

Instrumental analysis focuses on the use of instruments and techniques to analyze chemical samples, while other chemistry classes may cover more theoretical concepts. It also involves a lot of hands-on lab work and data analysis.

A basic understanding of math is required for instrumental analysis, as you will be using equations and calculations to analyze and interpret data. However, it is not necessary to have an advanced level of math proficiency.

Some common techniques used in instrumental analysis include spectroscopy, chromatography, mass spectrometry, and electrochemistry. These techniques are used to identify and quantify chemical compounds in a sample.

Conservators and conservation scientists use various forms of instrumental analysis to identify and characterize materials. In the example shown, Fourier Transform Infrared Spectroscopy (FTIR) was used to compare three photoreproductions all believed to be diazotypes, only one of which had been conclusively identified as such. The nondestructive analysis allowed conservators to determine that the unidentified objects were not chemically identical to the known diazotype, and that further study was needed to characterize them.

The book titled Principles of Instrumental Analysis, authored by Douglas A. Skoog, F. James Holler, Stanley R. Crouch is designed for the students of chemistry, biochemistry, physics, geology, the life sciences, forensic science, and environmental science to develop an understanding of these instrumental tools and their applications to relevant analytical problems in these fields.

Analytical instrumentation is crucial to research in molecular biology, medicine, geology, food science, materials science, forensics, and many other fields. Undergraduate Instrumental Analysis, 8th Edition, provides the reader with an understanding of all major instrumental analyses, and is unique in that it starts with the fundamental principles, and then develops the level of sophistication that is needed to make each method a workable tool for the student. Each chapter includes a discussion of the fundamental principles underlying each technique, detailed descriptions of the instrumentation, and a large number of applications. Each chapter includes an updated bibliography and problems, and most chapters have suggested experiments appropriate to the technique.

This edition has been completely updated, revised, and expanded. The order of presentation has been changed from the 7th edition in that after the introduction to spectroscopy, UV-Vis is discussed. This order is more in keeping with the preference of most instructors. Naturally, once the fundamentals are introduced, instructors are free to change the order of presentation. Mathematics beyond algebra is kept to a minimum, but for the interested student, in this edition we provide an expanded discussion of measurement uncertainty that uses elementary calculus (although a formula approach can be used with no loss of context). Unique among all instrumental analysis texts we explicitly discuss safety, up front in Chapter 2. The presentation intentionally avoids a finger-wagging, thou-shalt-not approach in favor of a how-to discussion of good laboratory and industrial practice. It is focused on hazards (and remedies) that might be encountered in the use of instrumentation. Among the new topics introduced in this edition are:

Thomas J. Bruno was group leader in the Applied Chemicals and Materials Division at NIST, Boulder, Colorado before retiring in 2019. He received his B.S. in chemistry from Polytechnic Institute of Brooklyn, and his M.S. and Ph.D. in physical chemistry from Georgetown University. He has published over 270 research papers, 8 books, and has been awarded 10 patents. He serves as associate editor of the CRC Handbook of Chemistry and Physics, and associate editor for Fuel Processing Technology.

The late Eileen M. Skelly Frame was the first woman commissioned from the Drexel University Army ROTC program, graduating summa cum laude in chemistry. She served as Medical Service Corps officer in the U.S. Army from 1975 to 1986, rising to the rank of Captain. She received her doctorate in 1982, and became the first female chemistry professor at the U.S. Military Academy at West Point. She was adjunct professor, Department of Chemistry and Chemical Biology, Rensselaer Polytechnic Institute (RPI), Troy, NY, and head of Full Spectrum Analytical Consultants. Dr. Skelly Frame passed away in January of 2020.

George M. Frame II earned his AB in chemistry from Harvard College, Cambridge, Massachusetts, and his PhD in analytical chemistry from Rutgers University, New Brunswick, New Jersey. He is a retired scientific director, Chemical Biomonitoring Section of the Wadsworth Laboratory, New York State Department of Health, Albany. He has a wide range of experience in analytical chemistry and has worked at the GE Corporate R&D Center (now GE Global Research), Pfizer Central Research, the US Coast Guard R&D Center, the Maine Medical Center, and in the US Air Force Biomedical Sciences Corps.
