Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 #293811840 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 Spectrometer is a versatile analytical instrument used to identify, quantify, and characterize the components of gas, liquid, or solid samples. This spectrometer utilizes spectral measurements to provide quantitative and qualitative insights into the samples. The centerpiece of this system is a high-resolution infrared or near-infrared spectrometer. This forms the basis for the operation of HP 7890 Spectrometer as it collects and analyzes the infrared radiation that is emitted and absorbed by the chemical molecules of the samples. In addition to the spectrometer, the instrument contains various components that aid in the acquisition and interpretation of the spectral data. These include a sample cell or holder, a sample interface, and the optics that direct the light from the source to the sample and from the sample to the detector. The cell or holder supports the sample during the measurement, while the sample interface separates the sample from the optical pathway. The optics contain beam splitters, mirrors, beam-shaping apertures, filters, and lenses that act to optimize the light transmission between the source and detector. The spectrometer also contains an array of precision components that control the range, resolution, and accuracy of the data analysis. These components include an adjustable wavelength selection filter, a variable aperture, and selectable signal processing algorithms. The filter allows the user to narrow the spectral range of the sample, while the aperture adjusts the amount of light that is detected. The algorithms allow the user to process the data to match the evaluation requirements, including spectral analysis, peak identification, peak measuring, and background subtraction. Finally, the system includes a wide range of software features for the user to review and interpret the data. The software provides tools for data acquisition, data processing, and visualization. It allows users to customize the operation of the spectrometer and the data analysis and includes features such as an integrated library for spectral data. AGILENT 7890 Spectrometer is an invaluable tool for the analytical chemist as it provides detailed data on unknown samples in a variety of formats. This information can then be used to develop new products, improve existing processes, or gain critical insights into the chemical and physical properties of the samples.
