Detection of malathion in food peels by surface-enhanced Raman imaging spectroscopy and multivariate curve resolution.

Abstract

An analytical methodology was developed for detection of malathion in the peels of tomatoes and Damson plums by surface-enhanced Raman imaging spectroscopy and multivariate curve resolution. To recover the pure spectra and the distribution mapping of the analyzed surfaces, non-negative matrix factorization (NMF), multivariate curve calibration methods with… (More)
