Resumo
A Multivariate Image
Analysis (MIA) laboratory activity was proposed estimating pH of drinking water samples from its digital images after adding
bromothymol blue as a pH indicator, and using the PLS multivariate calibration method. All computational work was done using
GNU Octave free software. The MIA-PLS based approach exemplified with drinking water pH estimates is tailored to meet the needs
of both students and researchers. MIA-PLS method was statically equivalent to the reference method using a conventional glass pH
electrode. This lab activity combines analytical methodology, computing, and chemometrics.
