More About CLS, Part 1: Expanding the Concept
A newly discovered effect can introduce large errors in many multivariate spectroscopic calibration results. The CLS algorithm can be used to explain this effect. Having found this new effect that can introduce large errors in calibration results, an investigation of the effects of this phenomenon to calibrations using principal component regression (PCR) and partial least squares (PLS) is examined.

Use of Handheld X-Ray Fluorescence to Analyze Platinum Group Metals in Catalytic Converters
The platinum-group metals platinum, palladium, and rhodium are essential and valuable elements in catalytic converters, and thus must be recycled. Handheld X-ray fluorescence (XRF) can be extremely beneficial for analysis of these metals in finely ground materials extracted from used catalytic converters.

The Importance of Fourier-Transform Infrared Spectroscopy in the Identification of Carbonate Phases Differentiated in Magnesium Content
In this study, FT-IR spectroscopy was used for identification of carbonate minerals in limestone with variable contents of magnesium. Associated spectral bands were identified and assigned. Results of studies of Triassic limestone samples taken from the area of the Polish part of the Germanic Basin using FT-IR are presented. The results of research show that substitution of Ca2+ by Mg2+ in the carbonate phase lattices leads to a continuous wavenumber increase in the assigned band locations.

Characterizing Microplastic Fibers Using Raman Spectroscopy
In this study, macro- and microscopic Raman spectroscopy were used to identify different commercial microplastic fibers using measured spectra with database searches. Raman microscopy is demonstrated as a powerful technique for microplastic fiber characterization, especially for samples that contain mixtures of components, including multiple polymers, or additives.
