1. A method of analyzing a liquid specimen, comprising the steps of forming a specimen support of a rigid material that is non-reactive to water and acidic substances and having a pair of opposed surfaces and having a plurality of unobstructed holes extending between said surfaces, a first of said holes having a different cross sectional area than a second of said holes, positioning said support so that said surfaces are horizontal and the axes of the holes are vertical, enclosing each hole with an unsupported film of a liquid specimen to be analyzed, directed a beam of infrared light through the hole and through the liquid film enclosing the hole, and generating a wavelength spectrum of said beam passing through said film.
