Used VARIAN 640-IR #293815184 for sale

VARIAN 640-IR is a thermally-stabilized Fourier Transform Infrared (FT-IR) spectrometer manufactured by VARIAN Inc. It is a highly sensitive and accurate spectrometer designed for the precise measurement of molecular composition. At the core of the instrument is a concave mirror-based interferometer which combines beams of near-infrared light to create a spectrum of signal intensity versus wavelength for the spectral sample. The instrument utilizes a gold-coated aluminum corrosion-resistant interferometer mirror to ensure high light throughput and excellent spectral resolution. The interferometer uses both Michelson and Kretschmann geometry designs, with the advantages of each to achieve reliable and consistent data. 640-IR is equipped with a purge control unit to regulate environmental conditions such as temperature and humidity, enabling accurate performance in fluctuating temperatures over prolonged periods, making it especially suitable for many industrial and research applications. In order to meet the requirements of modern FT-IR spectroscopy and to increase productivity, the equipment is capable of multitasking, recording up to eight spectra simultaneously in different regions of the infrared spectrum. The system is designed with a software-controlled data acquisition unit (DAS) to continuously monitor both the performance of the instrument as well as the sample composition. The DAS can store up to ten thousand spectra, enabling quick retrieval, plus it offers features such as peak fitting and subtraction of background for enhanced accuracy. The software machine also includes tools to assist users with the analysis and interpretation of spectral results. VARIAN 640-IR is equipped with an access port through which users can control the instrument from a PC for automated tests and remote operations. Advanced features such as RS-485 bus communication interface allows interfacing with laboratory networks and external devices. The instrument includes an advanced optical design which helps to minimize the effects of beam deviation and allows high throughput and signal-to-noise (SNR) ratios. To ensure safety during operation, 640-IR is designed with an alarm tool which indicates any malfunction. Additionally, the instrument is equipped with a safety interlock switch for the user's safety and convenience. All in all, VARIAN 640-IR is a high-performance FT-IR spectrometer designed with state-of-the-art technology and features, making it ideal for many research and industry applications. With its robust design, flexibility and intuitive user interface it is an ideal tool for precise spectral analysis and composition measurements.
