Pharmaceutical Surveillance with Multiple Distributed Portable Raman Spectrometers
Globalization of the pharmaceutical supply chain appears to be increasing the risk that pharmaceutical consumers will be exposed to drug products that have been adulterated. Traditional surveillance testing by collecting samples and sending them to labs for analysis is inefficient and time consuming. Higher efficiencies can be achieved by screening pharmaceuticals at site in order to selectively sample and further test suspect materials. Portable spectroscopic instruments are now readily available to support field testing of pharmaceutical materials. Methods developed on these instruments must be rapid and have the sensitivity required to identify contaminants in pharmaceutical materials. Finally, efficient procedures for method distribution must be developed so that calibration models need not be recreated on each individual instrument. This presentation will describe our development of portable Raman spectrometric methods for field analysis of diethylene glycol in glycerin.
