“…Miniaturized NIR spectroscopy shows potential as a tool for analyzing old photographs. The performance of a portable NIR spectrometer, in comparison with a benchtop ATR‐IR instrument, for the identification of historic photographic print materials was performed recently [122] . NIR spectroscopy enabled a deeper sensing of the inner layer of photography.…”

This review article focuses on the principles and applications of miniaturized near‐infrared (NIR) spectrometers. This technology and its applicability has advanced considerably over the last few years and revolutionized several fields of application. What is particularly remarkable is that the applications have a distinctly diverse nature, ranging from agriculture and the food sector, through to materials science, industry and environmental studies. Unlike a rather uniform design of a mature benchtop FTNIR spectrometer, miniaturized instruments employ diverse technological solutions, which have an impact on their operational characteristics. Continuous progress leads to new instruments appearing on the market. The current focus in analytical NIR spectroscopy is on the evaluation of the devices and associated methods, and to systematic characterization of their performance profiles.

“…In addition, the presence of coatings, lacquer layers (Figure 2(b)), or the use of alternative fabrication methods may make the interpretation of IR spectra even more difficult. 10 Because the coatings and lacquer layers overlap the IR spectrum of the proper pigment layer, ATR-FTIR technique may be more susceptible for misidentification of the photography. Compared to ATR-FTIR, NIR spectroscopy is characterized by a significantly higher penetration depth, which allows you to get information better averaged across the sample depth (Figure 2(b)) and the local (i.e.…”

Modern forensics encounters new challenges and demands new analytical methods that would meet variety of prerequisites regarding their accuracy, rapidness, flexibility, and reliability. Vibrational spectroscopic methods, in particular near-infrared spectroscopy, offer such potential and meet an increasing interest in forensics for authentication of various documents. Pittcon 2020 Conference, which took place in Chicago, Illinois, included a Session dedicated to the role of novel tools of investigation in the forensics of tomorrow. This article summarizes and complements the presentation upon how the current state-of-the-art and future prospects of vibrational spectroscopic techniques fits into this role. The application of near-infrared spectroscopy, including the benefits stemming from using novel miniaturized portable instruments, Raman and surface-enhanced Raman scattering techniques, is discussed in detail in the present article.

“…The DOP silver gelatin prints exist in abundance numbers in collections of archives, museums, libraries, historical societies, and family photograph worldwide. The layered structure of DOP silver gelatin print contains mainly three layers [4]: a paper support on which other layers are attached. It physically supports the photographic binder of gelatin, a highly purified protein produced mainly from hides and bones of animal wastes which holds the silver particles (i.e., the final image material) [5,6].…”

This study is the first involving the use of ethyl lactate as a green solvent on vulnerable photographs in an endeavour to protect the environment by using eco-friendly economic materials and methods in photograph conservation field. The paper is an experimental study aims at evaluating the efficiency of Ethyl lactate (E.L.) as an eco-friendly solvent in the removal of adhesive stains found on developed-out (DOP) silver gelatin prints. For achieving the paper objectives, three silver gelatin prints were stained with an adhesive and treated with three concentrations of E.L. The study assessment was implemented by digital microscope, atomic force microscope, and spectrophotometer to observe the changes which may occur on the surface post treatments; in addition to the use of attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy to investigate the gelatin binder layer after treatment. Moreover, the mechanical properties and the pH value were measured. The three concentrations of ethyl lactate were efficient in cleaning the surface without causing any damage to the structure of photographs. The paper proved the success of ethyl lactate treatments as an eco-friendly solvent in cleaning adhesive stains from developingout silver gelatin prints.
