Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 #9174126 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 Spectrometer is a high performance analytical instrument used for liquid chromatography (LC) and gas chromatography (GC). The instrument functions as a dual system allowing both LC and GC analyses to be performed at the same time. The GC-related components include a split/splitless injection port, a backflushing mercury-sealed capillary separation oven, two detectors - flame ionization (FID) and electron capture detectors (ECD). The LC-related components involve the injection system, six column ovens and three different detectors - ultraviolet-visible (UV-Vis), refractive index (RI) and evaporative light-scattering (ELS). To improve resolution and accuracy of the analysis, HP 7890 has a range of tuneable parameters. This includes a device that can control the temperature of the GC oven, the pressure of the capillary column, the polarity of the detector, the wavelength of the UV-Vis detector and the frequency of the backflush cycle. The spectrometer is also equipped with a detector interface that can control the magnitude, width and polarity of the current in the FID and ECD. This allows for the detection of a wide range of compounds including explosives, explosive precursor molecules, compounds with high boiling points, low boiling points and organometallic compounds. To ensure reliable measurements, the instrument has several quality assurance features. This includes a keypad audit trail that can be used to record operator actions, provide evidence of maintenance and calibrations, and store the analytical results. The spectrometer can be connected to a computer system to allow for the collection, review, storage and archiving of the data. AGILENT 7890 is designed to meet the requirements of industrial analysis and laboratory research. It is able to analyze samples quickly and accurately, with minimal operator assistance. It provides reliable and reproducible data in a range of formats, including graphical and numerical formats for easy presentation. The instrument is also designed with safety features to ensure safe operation, as well as prevent any accidental contamination of the sample.
