Used VARIAN 640-IR #9225992 for sale

VARIAN 640-IR is a permanent magnet double focusing spectrometer specifically designed for the analysis of infrared spectra. This spectrometer utilizes two (2) detectors—a digitizer and a CCD (charge-coupled device) detector—to collect and store the data generated by the beam of electrons passing through the sample being studied. The digitizer determines the exact point of intersection of the electron beam and the sample surface, while the CCD detector gathers the data of the energy released due to electron scattering as the beam passes through the sample. The data collected is then analyzed using algorithms to create a visible spectra, which can then be used to determine various properties of the sample under analysis. 640-IR spectrometer has an adjustable first spectral resolution that offers a range from 0.025 cm^-1 to 0.05 cm^-1. This allows for the analysis of extremely complex spectra as well as strong signals, meaning that a greater variety of samples can be analyzed in greater detail. The directional resolution is also adjustable, ranging from 0.05 cm^-1 to 0.1 cm^-1. VARIAN 640-IR spectrometer also has a broad range of applications, such as the analysis of the concentration of different materials in a sample, and the determination of molecular weight and structure. Additionally, 640-IR is capable of measuring the temperature-dependence of spectra, which can be used to characterize the properties of a sample at different temperatures. Lastly, VARIAN 640-IR is also capable of making measurements in both conventional and rapid scan mode. In Summary, 640-IR is a versatile spectrometer designed to analyze infrared spectra quickly and accurately. It is equipped with two (2) detectors—a digitizer and a CCD detector—to collect and store the data generated by the electron beam passing through the sample. The adjustable first spectral resolution and directional resolution offer a variety of measurement capabilities, while the temperature-dependent analysis and rapid scan mode make VARIAN 640-IR a powerful tool for the accurate analysis of a wide range of materials.
