TN 50834 - Kidney Stone Analysis Using a Nicolet FT-IR Spectrometer


The usefulness of FT-IR spectroscopy in the analysis of kidney stones is growing. In this note, spectra of pure components of kidney stones were measured, mixed and a set of spectral libraries were built. A special algorithm,created to calculate the content in the stone of various components, is described. Sample preparation methods and precision of the analysis are discussed, and examples of the use of the Kidney Stone Library & Analysis Kit are given.
