Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890B #293756978 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890B Spectrometer is a high-performance gas chromatograph equipped with a Mass Selective Detector (MSD). This sophisticated piece of instrumentation offers excellent performance and wide dynamic linear range for chromatographic and spectrometric applications. HP 7890B utilizes two columns, one for detector, and the other for injector, which offers superior injector accuracy and temperature control. The temperature of the injector is adjustable from room temperature to highest column temperature at 7.7°C /min ramp rate. The temperature range of the detector is from 20°C to 150°C. AGILENT 7890B has a built-in dual channel, autotuning unit that optimizes the separation of compound according to the given conditions. It also features an auto-replace function for embedded columns of up to 4 meters. Furthermore, it is equipped with a four-way digital valve and a refractive index detector (RI) that is suitable for the determination of non-volatile organics. The instrument also offers a built-in Chemstation software that allows settings to be saved and recalled so that the same procedure can be used multiple times without resetting. The software also allows up to 128 components to be measured in a single run. The front end of 7890B contains an electronic pressure control system that allows the user to select the desired flow rate. It also contains a touch screen display, where parameters can be assigned, and the unit can also be programmed for separate flow control and pressure control. HEWLETT-PACKARD 7890B provides reliable quantitative measurements of multiple components in a single sample thanks to its low noise pre-amplifier and its wide linear range. This makes it suitable for trace analysis. The pressure rating of KEYSIGHT 7890B is greater than 15 psig, and it has a power requirement of 115 volts/60 hertz. It is compatible with varied solvent systems and columns so long as they are compatible with the pressure ratings. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890B is one of the most advanced and reliable spectrometers available and offers superior performance for chromatographic and spectrometric applications. It is well suited for trace chemical analysis, and its auto-replace function for embedded columns of up to 4 meters ensures consistently accurate results.
