“…LIBS has also been tested in a variety of other forensic investigations, including document discrimination [88,209,210], fraud detection of a variety of industrial products [211], soil fingerprinting [212,213], and the study of human remains [214,215] or of samples taken from suspects [216]. The success of all these applications heavily relies on the performance of the multivariate chemometric methods used.…”

Laser-induced breakdown spectroscopy (LIBS) has become an established analytical atomic spectrometry technique and is valued for its very compelling set of advantageous analytical and technical characteristics. It is a rapid, versatile, non-contact technique, which is capable of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and even enables remote analysis. This review attempts to give a critical overview of the diverse progress of the field, focusing on the results of the last five years. The advancement of LIBS instrumentation and data evaluation is discussed in detail and selected results of some prominent applications are also described.

“…All writing inks consist of a dye component or a mixture of dyes, as well as a binding substance known as a vehicle composed of several solvents and additives responsible for the physicochemical properties of inks (including lubricants, corrosion inhibitors, emulsifying agents, buffers, surfactants, and various other components) [2][3][4]. All ingredients in the ink mixture can yield important analytical information to the forensic document examiner.…”

“…All ingredients in the ink mixture can yield important analytical information to the forensic document examiner. Therefore, it is better to use analytical techniques that can identify the variety of chemicals from which writing inks are composed [4]. The following dyes are most commonly used as a part of blue writing ink: victoria blue (VB), rhodamine B and 6G, the methyl violet group of dyes (pararosaniline with four, five or six methyl groups), crystal violet (CV), methyl violet (MV), tetramethyl-pararosaniline (TPR) and copper phthalocyanine, which has been used in ink dye manufacturing since 1954 [5].…”

This work is devoted to the extremely popular but poorly developed scientific and forensic problem of the estimation of the actual dates of inscriptions placed on paper and made by ballpoint pens. It is shown that the degradation of writing inks with time may be controlled via Raman spectroscopy and gas chromatography. The time intervals for the implementation of each of these methods were determined using the ratios of the Raman peak intensities as degradation characteristics rather than their absolute values. In turn, this eliminates the effect of the concentration of a dye. The mutual influence of the volatile components and dyes of writing inks was also investigated and the time interval within which such influence is critical was found. According to the obtained results, a new methodological scheme for determining the age of documents, which were created at least 40 months ago, was proposed.

“…Few reports have demonstrated the application of LIBS for the analysis of writing inks [5,[18][19][20] and only two for printing ink analysis [21,22]. One of these studies reported the use of LIBS and LA-ICP-MS to study the elemental composition of inks from more than 200 pens [5].…”
