Abstract

A procedure has been developed to determine the concentration of cocaine HCl in sugar matrices. Partial least squares (PLS) quantitative software was used to calibrate 100 - 0% cocaine in inositol, dextrose, lactose, and mannitol. Calibration correlation coefficients ranged from 0.999 to 0.977 depending on the frequency range and the standards used.
