Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A #293650045 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A is a gas chromatograph and spectrometer that is among the most popular tools used in environmental testing and applications. HP 7890A is designed to accurately analyze samples of gaseous substances and to separate those components, allowing users to observe patterns and trends in the data. AGILENT 7890A's gas chromatograph configuration includes a series of tubing, valves, and ports with a heated chamber and columns that are passed through separately. The heated chamber heats up the sample and as the sample moves through the tubing it is separated into its component structures through a process of differential movement. The columns use a porous solid support material and a stationary phase to separate components. As the sample is heated it travels through the columns, the individual molecules of the sample interact the stationary phase, causing them to be separated. To analyse the data, the spectrometer component of HEWLETT-PACKARD 7890A is used. The spectrometer works by first transforming a sample of material into a fine powder. This powder is then heated and a beam of light is directed into it, breaking it into its component components. These components will then emit different ranges of energy, which is then measured and analysed by the instrument. This data can be used to determine the chemical composition of the sample, allowing users to identify and quantify patterns and trends in the results. Additionally, KEYSIGHT 7890A can be programmed to repeat the testing procedures multiple times, providing consistent and repeatable results, allowing environmental engineers and researchers to accurately determine component concentrations in their studies. The ability to accurately and quickly measure components, in addition to its ease of use and ability to be programmed, make 7890A one of the most popular analytical tools for environmental testing and research.
