A device for holding samples to be analyzed using the infrared transmission spectroscopy comprised of three or more infrared transparent windows that creates unparalleled gaps while maintaining a consistent path length, which eliminates interference fringes and ensures that quantitative analysis can be achieved. The present invention allows the use of high refractive index material, silicon, as window material. The device using silicon windows can serve both purposes of sample storage and infrared measuring cell. All-purpose disposable sample holders are now possible. In one embodiment, a pre-assembled sample holder is most suitable for loading and analyzing flowable liquid samples. In another embodiment, a sample holder can be easily assembled after high-viscosity fluids and deformable solid samples are loaded. In an alternative embodiment, the device comprised of two or more infrared transparent windows and a reflective mirror can be used for quantitative analysis using transflection infrared spectroscopy.
