Application of Raman Spectroscopy to Analytical Chemistry: A New Type of Spectrograph.

One of the reasons for the resurgence of Analytical Chemistry to a prime position in the field of chemistry in both academic and industrial circles was the addition of instrumental analytical methods to its procedures; the most widely known of these being spectroscopy. For many years the analytical chemist had been using a closely related field in his colorimetric methods but this was of small importance compared to gravimetric and volumetric analysis. However, the need for rapid accurate means of analyzing large numbers of samples, many of them not easily handled by the older methods, led him in the direction of physical rather than chemical analysis, principally optical methods. In this he was greatly aided by the wartime researches leading to the improvement in optical instruments and materials.
