This video provides a tutorial in how to perform Principal Components Analysis (PCA) using SIMCA 14.1. All the basic functionality of SIMCA is explored using an example spectroscopic dataset. • The dataset is MIR spectra of fresh meats, sourced from • https://csr.quadram.ac.uk/example-dat... • 120 Mid-infrared (MIR) spectra of fresh minced meats – chicken, pork and turkey. Duplicate acquisitions from 60 independent samples. Raw data matrix size [448 x 120]. Obtained using Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR) sampling. As described in “Mid-infrared spectroscopy and authenticity problems in selected meats: a feasibility study“ Al-Jowder O, Kemsley E K, Wilson R. H.(1997) Food Chemistry 59 195-20.
