摘要:
A new quartz spectrograph for absorption spectrophotometry is described. The method is a modification of the usual photographic method. A very wide spectrogram is divided into transverse comparison strips by means of a grid over the photographic plate, as first proposed by Jones. The instrument offers certain important advantages, among which are high speed, predetermined spectral distribution of absorption data, certainty of obtaining values at absorption maxima and other definite wave‐lengths, need for fewer photographic plates, and applicability to solids as well as to solutions and other liquids.
