Application of ATR-FTIR spectroscopy in tandem with chemometrics for assessing the firing conditions of Hellenistic and Roman ceramic shards excavated from the ancient city of Stratonikeia in South-Western Turkey

Recent advances and applications to cultural heritage using ATR-FTIR spectroscopy and ATR-FTIR spectroscopic imaging

“…169 ATR-FTIR spectroscopy combined with principal component analysis (PCA) has been utilised to classify Hellenistic and Roman ceramic shards and determine their firing temperature. 182 XRD is the most commonly used technique to conduct qualitative and quantitative analysis of mineralogical sample. 183 ATR-FTIR spectroscopy combined with partial least squares (PLS) regression method has been utilised as an alternative technique to XRD to quantify 7 groups of minerals in archaeological and cultural heritage samples containing clay material.…”

“…To help analyse FTIR spectra, chemometric methods have been applied to assess variations between the spectra as discussed in this review. 6,92,93,108,114,182,189,194 The chemometric methods can categorise the samples and also cope with distorted spectra, contributing enormously to data analysis. It is hoped that the combination of spectral data bases, chemometrics and portable ATR-FTIR spectrometer 195 can be developed and commercialised.…”

An archaeometric study of the Konya basin metallic ware through FTIR and XRD analysis with chemometrics: Central Anatolian Early Bronze Age ceramics

“…A second‐derivative analysis was employed on FTIR data in order to identify underlying peaks and assign the mineralogical composition of the samples. This process is a highly efficient method for the identification of peaks that are otherwise not clearly detectable on the raw FTIR spectra, as it enhances the resolution (Ami et al, 2013), and is widely applied in the mineralogical investigations of ceramic samples (Akyuz et al, 2019; De Benedetto et al, 2002; Shoval et al, 2011; Shoval & Paz, 2015; Tarhan et al, 2021).…”

Antimicrobial Agent against Methicillin-Resistant Staphylococcus aureus Biofilm Monitored Using Raman Spectroscopy

“…A chemometric approach was used to identify the correlation between Raman peaks and MRSA biofilm growth. To obtain a simple biological interpretation of the results, principal component analysis (PCA) was used and is a powerful multivariate analysis tool for exploring and interpreting high dimensional data in many fields [ 15 , 16 , 17 , 18 ]. The algorithm was used to determine if minor differences among MRSA biofilm cell structures could be differentiated based on their individual spectra.…”
