The advent of robust, rugged, and current Good Manufacturing Practices
(cGMP) compliant hand-held Raman spectrometers provides a wealth of
opportunities for the analytical pharmaceutical chemist to bring the
laboratory to the sample. This paper discusses the use of hand-held
Raman spectrometers for the development of qualitative chemical
identification methods for a number of well-known pharmaceutical
products (tablets and capsules). Methods were developed on two different
instruments and transferred to a third instrument for application of the
methodology to independently obtained drug products. A novel decision
algorithm is presented for the assessment of the correlation between the
Raman spectrum of the unknown sample to the spectrum of the authentic
reference material. This novel algorithm considers accuracy but more
importantly precision (uncertainty/reliability), thus removing human bias
that is associated with typical spectral searching approaches. The results
presented in this paper show the reliability of developing, validating, and
transferring chemical identification assays on hand-held Raman spectrometers.
