Compatable with measurement standards Methodĭetermination of fatty acid methyl ester (FAME) content in middle distillates. The constant pathlength makes the cell ideally suited for quantitative analysis. Each sealed liquid cell has a precise pathlength that is calibrated using interference fringes generated by the empty cell in the beam of a spectrometer. The resulting bond between the window and lead spacer provides a corrosion-resistant leak-free seal for preventing evaporation and loss of sample. The sealed liquid transmission cell has the window pair and spacer amalgamated as an assembly. It is particularly well suited for samples that are hard to clean. The sample is introduced via filling ports, and the transmission cell is easily disassembled for cleaning. Spacers of various thicknesses can be used to vary the cell pathlength. It comprises rectangular windows and an appropriate spacer. a Nic-Plan FTIR microscope coupled with a Nicolet 5700 FTIR spectrometer. This configuration is a general purpose liquid transmission cell. Fourier transform infrared spectroscopy (FTIR) can be used to identify or. This design makes the cell ideally suited for analyzing very viscous liquids, gels, mulls, and pastes. The data was acquired with the Nicolet software Omnic at 0.5 cm-1. Spacers of various thicknesses can be used to vary the cell pathlength. A Fourier Transform Infrared FTIR spectrometer was used to analyze the composition. The sample is placed directly onto one of the circular windows, and the other window is then placed lightly on top. This configuration uses circular windows without filling ports. The Omni Cell transmission cell is available in three configurations: Mull Transmission Cell This transmission cell is specially designed to be suitable with both FTIR and dispersive instruments, and is available with a wide variety of high-quality window materials to meet your analytical needs.

Specac’s Omni Cell System presents a novel approach for the analysis of liquid, mulls, pastes, and cast film samples in UV, Vis, NIR, and IR transmission spectroscopy, with one cell mount being suitable for all applications.
