<p>The present invention more specifically discloses in an infrared spectrometer which includes an infrared source, an optical array, an infrared detector and a means for recording transmitted spectrum over a range of wave numbers; the improvement which comprises the infrared spectrometer including a sample carrier which is comprised of a mesh which is opaque or totally transparent to infrared light, wherein the holes in the mesh have a minimum size that is sufficient to allow particles having a particle size of smaller than 25 microns to pass through the mesh and a maximum size that will hold particles having a particle size of greater than 841 microns. It also discloses a suitable sample carrier and a process for determining the infrared spectrum of a sample. <IMAGE></p> |
