Determination of Pesticides in Flour by Terahertz Time-Domain Spectroscopy (THz-TDS) with Voigt Function Fitting and Partial Least Squares (PLS) Analysis

Terahertz time-domain spectroscopy (THz-TDS) has been used to analyze mixtures of imidacloprid, carbendazim, and flour substrate. A multiple spectra baseline correction (MSBC) method was adopted to...
