Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890B #293609895 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890B is a spectrometer designed for gas chromatography. It is a highly advanced digital sensing and control device that is capable of providing a reliable chromatography separation with maximum efficiency. HP 7890B contains a precision-engineered, digital thermoelectric heat exchanger that is programmed to heat the sample. This is done precisely at the desired temperature and a pulse-width-modulated solenoid is used to provide a steady flow of sample from the sample loop valve to the column. The spectrometer is equipped with a highly sensitive flame ionization detector (FID) that allows for accurate detection of analytes. This FID is attached to a heated inert gas purger that helps purify the gases used in the analysis. The spectrometer also has an on-board electronics module designed to control the gas flow rate and temperature. Along with the FID, AGILENT 7890B also has a closed loop turbulent flow control system which is designed to maintain optimal chromatographic performance. This ensures that the sample's temperature and pressure are regulated to minimize temperature and pressure fluctuations during analysis. This is particularly useful when analyzing samples that may have high boiling points, such as carbohydrates and sugar solutions. Other features of the spectrometer include an on-board computer that can store data and maintain critical operating parameters. This includes programming the FID parameters such as the sensitivity, speed and resolution, along with other important indicators such as the sample injection time and the flow rate. KEYSIGHT 7890B also has an on-board USB port for easy connection to a computer for data transfer and data analysis. 7890B's high performance and advanced features make it ideal for a variety of uses in research laboratories, medical facilities, and product testing centers. Its ease of use, versatility and durability make it an excellent choice for a variety of chromatographic purposes. Furthermore, its digital software and integrated hardware offer unprecedented accuracy, reliability and efficiency in measuring compounds with complex matrices.
