Abstract
Minimization of samples for infrared spectral measurement was attempted by the use of a Japanese folkcraft, hand-made paper, impregnated with liquid paraffin. By this method, it is possible to measure 0.1 mg. of a sample. This hand-made paper was also used for paper chromatography and the developed paper was submitted directly to infrared spectral measurement. Component of Penicillium islandicun and inorganic sulfate ion were determined by spectral measurement of their chromatogram.
