Dust particles smaller than 10 microns are partially transparent to X-rays so that the measured absorption should be sensitive to ALL atoms in both gas and solid phase. High resolution X-ray spectroscopy, as currently possible with the Chandra X-ray satellite can therefore provide a powerful and unique tool for determining the state and composition of interstellar material, since dust grains along the line of sight will imprint oscillatory features (X-ray absorption fine structure - XAFS) near photoelectric edges. I will show how we have begun to determine dust composition through XAFS signatures using laboratory solid state work in complement with space (Chandra and Spitzer spectra) studies to determine and differentiate dust composition along different lines-of-sight, and in different environments.
