Abstract

Based on several years' experience, the substitution of commercial sheet film for glass plates is advocated for spectrochemical purpose. Advantages of sheet film are freedom from breakage, ease of cutting and filing, and ability to photograph wide spectral regions in one piece. Commercial emulsions are more uniformly coated and are much more free from blemishes. Holders for glass plates can be used for film with no structural changes. A list of available emulsions which can be used in place of spectroscopic plates is presented.
