Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A #9394902 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A is a highly accurate and reliable gas chromatograph (GC) equipment featuring a modern and powerful automated sample handling platform. It provides reliable and repeatable performance for a wide range of gas chromatography applications. HP 7890A has two injector ports, each with inert construction, enabling the injection of multiple samples at once. The sample injection system is precision-controlled with up to 0.5μl increments to ensure accuracy and reproducibility. An internal ultra-low carryover injector cartridge helps eliminate the need for manual cleaning between sample injections. The built-in liquid isothermal oven provides rapid heating and cooling cycles that can be readily optimized for applications requiring precise temperature control. The temperature standard deviation is as low as 0.25°C and the temperature ramp can be set at 0.1°C per second or slower for improved resolution. Additionally, the temperature of the oven can be precisely controlled from ambient conditions up to 350°C. AGILENT 7890A spectrometer uses a high-resolution, single quadrupole mass spectrometer (QMS), providing accurate quantification of compounds. The quadrupole mass spectrometer is equipped with two universal ionization modes, electron impact (EI) and chemical ionization (CI), enabling detection of both polar and non-polar components. The integrated data processor with optimized electronics amplifies the signals generated by the data acquisition electronics and permits trace analysis. The data acquisition unit also records chromatographic and mass spectral information, making it possible to construct a chromatogram or a spectrum for each injection. 7890A is compatible with multiple communication protocols, including GPIB, USB, and Ethernet. This allows for remote operation of the machine and the addition of automation solutions. The integrated 768 MB RAM memory capacity permits storage of chromatogram data produced from a large number of chromatographic runs. For automation, the Flexible Sample Introduction Tool (FSI) is available. This allows users to efficiently route samples between injectors, and between the injectors and detectors. The FSI can also carry pumps, samplers, and a variety of automated detection systems. KEYSIGHT 7890A Gas Chromatograph asset has been designed for top-end performance and yields excellent chromatography data in combination with excellent automation and instrument management. It is an ideal choice for industrial or research laboratories looking for enhanced analytical throughput, safety, and reliability.
