  • Spectroscopic sample holder and method for using same
    Patent number: 5470757
    Abstract: A sample holder for use in infrared spectrophotometric analysis. The holder comprises a microporous sheet and is particularly useful for analysis of solutions, colloids, small particle solids, flowable solids, solvents, and viscous fluids. The microporous sheet preferably has a low absorbance (high spectral transmittance) in infrared wavelengths. The sample holder is especially useful for the analysis of aqueous based samples. Also, a method for using such sample holders for infrared spectrophotometric analysis.
