Device for multisample infrared analysis of materials in microgram quantity

摘要

A sampling device adapted for mounting on a conventional microsampling apparatus for infrared spectroscopy is arranged to sample a plurality of different samples of unknown material during one operation. The device supports by a clamp an IR-transparent substrate on which solutions of samples are deposited. After evaporation of the solvent, the residue of unknown material is analyzed by conventional spectroscopy procedures. Each of the plurality of such samples deposited on the substrate are manually rotated into and out of exposure to the IR beam of the apparatus for rapid analysis.
