An empirical evaluation of ATR-FTIR-PLS for the determination of total aflatoxins in food grains and poultry feed and populations' exposure risks assessment in Malaysia and Nigeria
Below is the raw data used for the validation process in the above-mentioned research. A total of 224 dilutions of Mixed aflatoxin standard solution were prepared in (a) 75% methanol solvent (112 samples) and (b) 100% acetonitrile solvent (112 samples). Each dilution set ( a and b) contains 16 concentration levels ranging from 0 to 90 ng per ml of the mix aflatoxin standard solution. ATR-FTIR spectra of both dilution sets were collected. The various absorbance with respective wavenumber was recorded. Data were analysed using MINITAB 18 statistical software; a PLS model was developed and validated using the data. The files below showed the raw data and the analyses.
