Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A #9235843 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A Spectrometer is a high-performance, single-quadrupole mass spectrometer of the highest quality. First introduced in 2002, HP 6890A stands as a robust, reliable, and accurate entry-level instrument for its price range. With capabilities for Electron Ionization (EI) and Chemical Ionization (CI) ion sources, the equipment comes equipped with a range of standard features and options that allow for an extensive range of applications from basic trace level analysis to ultra-trace level applications. AGILENT 6890A performs various mass spectrometry techniques, including Electron Impact Ionization (EI) and Chemical Ionization (CI). EI uses a hot filament to vaporize samples into individual compound ions to measure their mass-to-charge ratios (m/z). CI is suitable for both volatile and non-volatile organic analytes; it utilizes reagent gases such as oxygen to induce ionization and relies upon fragmentation of the sample for identification. At the heart of this system lies the Quadrupole Mass Filter, which allows for precise mass analysis by dispersing an ion beam. This is achieved by controlling the potential applied to the four rods that form the filter, allowing only ions with a specific mass-to-charge (m/z) ratio to pass through. Multiple potentials and filter settings can be defined to provide accurate separation and quantification of the ions. 6890A provides excellent ionization efficiency with its large source size and temperature control which can be placed in a wide range of temperatures from room temperature to 600° Celsius. Additionally, it can be operated in both positive and negative ion modes, providing concentrations of up to 107 amu/V. The instrument can also be fitted with a range of optional detectors, enabling the unit to be adapted to various sample types, analysis conditions, and requirements. These detectors include electron multipliers, micro-channel plates, and dynodes, all of which are impervious to the effects of noise and other atmospherically generated factors. Finally, KEYSIGHT 6890A can also be quickly configured to run manual methods, allowing experienced users to perform complex measurements from introduction to results in as little as 15 minutes. This allows a wide range of laboratories to take advantage of the machine's superior performance without the need for extensive training. Overall, HEWLETT-PACKARD 6890A is a powerful and reliable mass spectrometer for research and industrial applications. With its exceptional performance in ionization efficiency, separation, and detection, as well as its reasonable price point, AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A is an excellent choice for anyone looking for an entry-level instrument.
