Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A #9252991 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A spectrometer is a state-of-the-art analytical instrument that allows scientists to get a detailed understanding of a sample's chemical, physical, and optical properties. HP 7890A is a high performance gas chromatograph (GC) equipment which provides results with exceptional sensitivity, accuracy, and selectivity. AGILENT 7890A spectrometer consists of two main components; the GC and a detector. The GC part of the spectrometer separates the components and the detector measures them. The GC has a column oven, the injector, the transfer line, the detector, and the vacuum system. The injector introduces the sample into the oven and its controlled heating vaporizes the sample. The transfer line transfers the vapors from the oven to the detector. The detector captures the appropriate signal from those vapors. In order to maximize the lifetime of the unit, the vacuum machine controls the flow of the carrier gases such as hydrogen or nitrogen to the transfer line, allowing the GC to run at optimal efficiency. The detectors used in 7890A are of two types; the Flame Ionization Detector (FID) and the Mass Selective Detector (MSD). The FID is used to measure compounds that are not volatile, and the MSD can measure the molecular weight of a wide range of compounds. The detectors are very sensitive and have a wide dynamic range. This allows for very precise and accurate detection of trace and major components in a sample. HEWLETT-PACKARD 7890A is a very versatile tool, it can be used for a variety of applications. It can be used to detect pollutants from industrial or environmental samples, to search for adulterants in food products, to analyze petrochemicals, and to study pharmaceuticals. It can also be used in research and development applications to develop new products or analyze new formulations. Overall, KEYSIGHT 7890A spectrometer is a powerful tool with a wide range of applications. Its flexibility, accuracy, and capability allow it to provide results with unparalleled value.
