Abstract Hyperspectral imaging is a technique that combines spectroscopy and imaging. Originally utilized in the 1980’s by the remote sensing community it is now utilized in a wide variety of applications. Spectral imaging was first used for the detection of compression wood in the late 1990’s and since that time research focused on wood and wood products has steadily increased with a variety of applications reported. While there are several reviews of wood related research utilizing near infrared spectrometers a comprehensive summary of wood—hyperspectral imaging research is lacking. Near infrared hyperspectral imaging systems (NIR-HSI) typically have a wavelength range of 900–1700 nm, whereas short-wave infrared hyperspectral imaging (SWIR-HSI) systems range from 1000 to 2500 nm. We provide a detailed account of the various studies that have been published utilizing both camera types.

Abstract Volatile organic compounds are a broad and important class of pollutants affecting the indoor air quality. They are emitted from commercial products, building materials, furniture, occupant activities and even occupants, etc., and can participate in the indoor chemistry reacting with oxidants or being formed from secondary reactions. Some VOCs are classified as carcinogens and are associated with a variety of health effects. Characterizing and quantifying the VOCs in the indoor environments is of paramount importance in order to implement preventive measures to minimize the human exposure. A correct assessment of human exposure or characterization of emission sources and indoor activities requires appropriate and efficient methods for sampling and analysis. Therefore, this review focuses on the different methodologies for monitoring VOC that must be selected when a sampling plan is designed considering the objective of the measure. Selecting the most suitable procedures for assessing VOCs requires proper knowledge on the existing standards and off-line (including the selection of the sorbent media) and online instrumentation. Knowing the advantages and drawbacks of the different techniques available can help to plan future studies.

Abstract Radicals and their precursors play a central role in the chemical transformations occurring in indoor air and on indoor surfaces. Such species include OH, HO2, peroxy radicals, nitrous acid, reactive chlorine species, NO3, N2O5, Criegee intermediates, and glyoxal and methylglyoxal. Recent advances on instrumental analysis and modeling studies have demonstrated the need for a wider range of measurements of radical species and their precursors in indoor air. This work reviews measurement techniques and provides considerations for indoor measurements of several radicals and their precursors. Techniques to determine the actinic flux are also presented owing to the relevance of photolytically-initiated processes indoors. This review is also intended to provide pointers for those wanting to learn more about measurements of radicals indoors.

People in developed countries are estimated to spend 80–90% of their time indoors, where they can be exposed to poor air quality from numerous and diverse sources. These include mold growth and other microbial pollutants in humid air, to the chemical pollutants that result from emissions from human activities such as cooking, cleaning, smoking and home refurbishments. In fact, the concentrations of many air pollutants can be higher indoors than out, particularly following activities such as cleaning and cooking. Despite these facts, regulation for air pollution focuses mainly on outdoors and the indoor environment is much less well characterized or indeed regulated. With increasing climate change impacts expected in the future, related energy efficiency measures are making buildings considerably more airtight leading to the potential for even higher indoor air pollutant concentrations. Therefore, to reduce our exposure to air pollution, we must consider air pollutant sources and sinks in both the indoor and outdoor environments. We also need to consider the role of ventilation in mixing air between the two, in order to mitigate through appropriate building operation, use and design. Cost Action 17136 INDAIRPOLLNET (INDoor AIR POLLution NETwork) aims to improve our understanding of the cause of high concentrations of indoor air pollutants. It assembles experts in chemistry, biology, standardization, particulate matter characterization, toxicology, exposure assessment, building materials (including green materials), building physics and engineering and building design, performing laboratory and chamber experiments, modeling studies and measurements of relevance to indoor air quality, including outdoor air chemists. This Action is significantly advancing the field of indoor air pollution science, and highlighting future research areas, as well as aiming to to bridge the gap between research and business. In this way, we will be able to identify appropriate mitigation strategies that optimize indoor air quality. One of the objectives of our Action has been to explore the best ways to measure key indoor air pollutants given specific requirements (research question, available funds, building location and characteristics etc.). This special issue therefore summarizes the various measurement techniques that are currently available for indoor air measurements and the advantages and disadvantages of each for the indoor environment.

Abstract Particulate matter (PM) is an important player in indoor air quality. Even though PM limit values are in force for more than a decade in Europe and reference methods are well in place for ambient air, measuring indoor PM concentration still remains a challenge and standardizing a measurement protocol is complex. As people stay most of their time indoors, indoor PM is of great interest in terms of public health, as concentration can be drastically different to the one outdoors. This review aims to provide key information to the indoor air monitoring communities, to better understand principal methods suitable for the analysis of indoor PM with their respective main influencing parameters. Advantages and drawbacks of each method are discussed and specific awareness is raised to avoid wrong data interpretation in specific situations. The inter-instrument deviation is also explained and, when possible, methods to correct are proposed.

Abstract A review on the design of quartz tuning forks and their applications in quartz-enhanced photoacoustic spectroscopy (QEPAS)-based trace gas sensors is reported. Standard commercial quartz tuning forks are used as sound wave transducers in the conventional QEPAS technique. With the development of QEPAS technology, the advent of custom quartz tuning forks has further improved the sensitivity level of QEPAS sensors. The manufacturing process of quartz tuning forks will be explained in detail in this review and the application of quartz tuning forks in QEPAS trace gas sensors in recent years will be summarized.

Abstract In this review, general aspects of the combination of the solid phase extraction (SPE) with energy dispersive X-ray fluorescence spectrometry (EDXRF) for multielement determination are presented. Derivations of SPE, such as dispersive solid phase extraction (DSPE), dispersive micro-solid phase extraction (DµSPE), and dispersive magnetic micro-solid phase extraction DM-µSPE are also presented, showing the possibility of direct analysis of the solid phase. The sorbents, advantages, disadvantages, and the analytical characteristics of the combination followed by direct determination of analytes retained on the solid phase are discussed. Furthermore, the perspectives of this analytical arrangement are presented.

Abstract This review summarizes current trends in direct through-container Raman spectroscopic analyses of housed samples without external sampling. Nonsampling Raman measurement is a relatively simple technique that avoids damaging or contaminating a sample’s commercial value by opening the container. The most demanding aspect of such techniques is the need to minimize or eliminate spectral interference from the container when analyzing the housed samples. To reduce the spectral peaks associated with the container, which can be either fluorescent or nonfluorescent, various measurement configurations, including spatially offset Raman scattering and/or algorithm-based background subtractions, have been employed. Here, reports on the former technique are categorized according to their analytical purposes into qualitative chemical identification and quantitative determination of component concentrations of housed samples. Studies in each group are further classified by container material, either glass or polymer (plastic), as the optical properties of each, as well as the dominance of their Raman spectral peaks, are different. Prospects for advances and unresolved issues in through-container Raman measurement are also discussed.

Abstract Human health is a subject matter that requires a multifold strategy starting by understanding the molecular basis of diseases, development of diagnostic approaches, and subsequently by finding possible innovative treatments. Neurodegenerative diseases, degenerative medicine, diabetes, preeclampsia, and pharmaceutics are just a few examples to mention. Therefore, the challenge for the scientific community is to develop new and creative means for acquiring, processing and interpreting the biomolecular information involved with tissues, single cells or cells in a microenvironment, at cellular and sub-cellular resolution. Synchrotron facilities open the door for a huge number of biological and biomedical applications, where high spatial resolution and high quality information are a must. This review highlights the strong role that the Synchrotron radiation-FTIR microspectroscopy (SR-μFTIR) plays in various biomedical fields with a special focus on the above-mentioned cases.

Abstract Spectroscopic studies of molten electrolytes have been carried out for more than 50 years. The information available in the literature on the problems arising in high-temperature spectroscopic measurements of molten electrolytes, as well as methods and technical solutions to overcome them, and the design of optical heating cells used for these purposes is fragmentary. The purpose of this review is to summarize the information available in the literature on techniques and methods for high-temperature spectroscopic measurements of molten electrolytes. A description of various techniques used in spectroscopic studies of molten electrolytes, including IR transmission spectroscopy, reflection and emission spectroscopy, reflection-adsorption spectroscopy, spectroelectrochemical Raman and IR spectroscopy is presented. A description of the design of the corresponding optical heating cells is given, as well as examples of spectra obtained using them. The review is useful for researchers studying electrolyte melts and specialists developing medium-temperature chemical current sources based on them. GRAPHICAL ABSTRACT
