  • Objective To develop a rapid method for the detection of toxic adulterant (diethylene glycol) in pharmaceutical excipient (glycerol). Method The detection sensitivity of Raman/ near infrared (NIR) spectroscopy combined with moving window correlation coefficient (MWCC) method was evaluated. Results The detection sensitivity of Raman spectroscopy was superior to that of NIR spectroscopy and with the assistance of MWCC method; the sensitivity had been further improved. Conclusion Raman spectroscopy has the potential to become the effective method in the on-site detection of toxic adulterant in pharmaceutical excipient.
