Abstract
A sample holding array is provided which is particularly advantageous for various IR and near IR transmission spectroscopy analysis that yields high quality spectra with minimal artifacts. The sample holding array may also be used desirably with slight modifications for Raman analysis, x-ray fluorescence and nanoindentation.
Claims9
A sample holding array for retaining multiple samples for the purpose of infrared or near infrared transmission spectroscopy comprising:
- a. a sample support which is at least partially transparent to infrared and near infrared radiation, the support having a first generally planar surface and a second opposed generally planar surface, the support being constructed of a material of the group consisting essentially of silicon, germanium, zinc sulfide, cadmium telluride, AMTIR-1, sapphire, KRS-5 or zinc selenide, the material of construction not containing impurities significantly detrimental to transmission of infrared or near infrared radiation through the thickness of the support, the support having a thickness which allows sufficient IR transmission to allow infrared and near infrared radiation transmission through the support for the purpose of spectroscopic analysis, and
- b. an array of individual sample cavities defined adjacent to said first planar surface of the support, the cavities being in optical communication with the second planar surface of the support whereby infrared or near infrared radiation can be transmitted through the thickness of the support for the purpose of spectroscopic analysis of samples contained in said sample cavities, respectively.
