“…12). 65 The upper spectral region, above 850 cm -1 , exhibited striking similarity to bands attributed to Si-O stretchings. The strongest band at 920 cm -1 was precisely assigned to the symmetric stretching mode of the SiO4 tetrahedra.…”

“…How-ever, it was later discovered that these bands were actually caused by laser-induced fluorescence from the presence of rare earth element (REE) impurities in the specimen providing detailed explanation and theoretical background regarding their occurrence. 65 This perplexing situation highlights the possibility of incorrectly assigning certain bands in FT-Raman vibrational spectra, which could lead to erroneous mineral identification. Similar observations have been made in other fields, such as cement minerals, 66 calcium minerals, [67][68][69] dental materials, 70 and bioceramics.…”

Many analytical methods have been successfully employed for the study of minerals, in particular, vibrational infrared (FTIR) and Raman spectroscopies and X-ray powder diffraction (XRPD). The advantages of the vibrational spectroscopic techniques for identifying and characterizing minerals include: rapid and versatile use; qualitative and quantitative chemical signatures; distinctive chemical fingerprint of a material; indirect determination of the crystal features (polymorphism, isomorphism, coordination, degree of deformation of structural polyhedra); small sample quantity (area less than 1 μm2 for Raman); wide coverage of 4,000 – 50 cm−1 region in a single scan; in situ and direct measurements without sample preparation; nondestructive use; etc. On the other hand, XRPD is a destructive technique that, depending on the method used and the density of the material, requires from a few micrograms up to around 5 grams of sample quantity for analysis. In spite of that, it is a rapid and powerful technique used in mineral studies with relatively straightforward interpretation of the results. During the last decade, portable X-ray powder diffractometers for the nondestructive analysis of art and archeological materials have been developed along with the portable and hand-held vibrational spectroscopy instrument. Here, some advantages and limitations in the process of the complementary use of FTIR and Raman vibrational spectroscopy and XRPD for identification and characterization of minerals are outlined.

“…A simple and efficient method for the detection of traces of rare earth elements in minerals by Raman spectroscopy was proposed in ref. [36]. It has a lower detection limits for the rare earth traces in minerals (analytically important), but can even be extended to serve as a convenient experiment for undergraduate and postgraduate laboratory courses.…”

It is both rewarding and difficult to write a review article about the contributions of academician Gligor Jovanovski to the study of minerals from Macedonia.It is rewarding because these contributions are exceptional scientifically and, in addition, serve as a clear sign for the existence of a country named, despite denials from some quarters, Macedonia or, more fully, Republic of Macedonia.On the other hand, it is difficult to briefly summarize the content of over 50 scientific papers, published mainly in distinguished international journals and cited many, many times in the scientific literature.Since this review article is published in the present special issue dedicated to academician Gligor Jovanovski, accepting the challenge I now try my best to give the reader a fair presentation of the content of the papers on minerals from Macedonia and a deserved tribute to their author.It should be noted that the work on the minerals from Macedonia does not cover all research interests of academician Jovanovski and that the reviewed papers deal with studies in several scientific fields. The early papers dedicated to the study of minerals from Macedonia are spectroscopic in nature (at first by conventional infrared spectroscopy and later enriched by the use of Raman and FT IR spectroscopy). Such a state of matters is a natural consequence of the availability of spectroscopic equipment, on the one hand, and the active spectroscopic work at the Institute of Chemistry of the Faculty of Science, on the other. Needless to say, a number of co-workers from the Institute of chemistry actively participated throughout in the studies by academician Jovanovski as may be seen in the list of references given below. Without having X-ray diffraction instrumentation on hands, Jovanovski devoted a respectable portion of his research of minerals to crystallographic (X-ray) studies. Clearly, such studies would not have been possible without the open-handed cooperation of researchers from Zagreb and Uppsala and the perseverance of Jovanovski himself. As the instrumental basis of the Institute of Chemistry grew and diversified and as an active research practice using the corresponding techniques took place, in his portfolio Jovanovski included the work with atomic absorption spectrometry (AAS) atomic emission spectrometry with inductively coupled plasma (AES–ICP) and neutron activation analysis. Again, some of these studies were carried out in cooperation with researchers from institutions where the corresponding equipment was available.

“…[28] Pretreatment of samples, correction standards and other techniques such as Raman and X-ray fluorescence have also been used to measure REE in geological samples. [29][30][31][32][33] Although the measurement of REE by ICP-MS is demonstrated to be accurate and reproducible, the proper preparation of materials for ICP-MS is crucial for accurate results. A comparative study of REE in geological reference materials using INAA and ICP-MS showed that ICP-MS was more accurate for light REE (La-Gd) compared to heavy REE (Tb-Lu), but determined that INAA produced results closer to literature values and suggested that sample preparation for ICP-MS was the cause.…”

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is used to measure the concentrations of rare earth elements (REE) in certified standard reference materials including shale and coal. The instrument used in this study is a Perkin Elmer Nexion 300D ICP-MS. The goal of the study is to identify sample preparation and operating conditions that optimized recovery of each element of concern. Additionally, the precision and accuracy of the technique are summarized and the drawbacks and limitations of the method are outlined.
