AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A is a gas chromatograph (GC) spectrometer from HP. It is used to characterize components in a mixture by separating the compounds based on their differences in volatility and affinity for a stationary coating on the inner walls of a narrow tube, the column. This instrument features a pre-column injector, a column oven, a detector, a recording device, an alphanumeric keypad and a monitor. The injector is designed to throughly disperse sample and buffer solutions into the column to produce a better chromatographic resolution of the compounds. The oven is used to ensure a stable, temperature-controlled environment that maintains the flow rate and heat history of the sample. The detector of HP 7890A is a flame ionization detector (FID), typically used for hydrocarbon and organic compound analysis. This detector consists of a fuel cell, a flame, and a temperature monitoring probe. The fuel cell provides the fuel and oxidants that are injected into the flame to combust the sample gas components. The temperature monitoring probe measures the sample temperature and maintains it in the optimal range. The recording device of this instrument is a digital oscilloscope connected to a recorder. This device can detect even subtle changes in the signals of the detector and provide advanced post-sampling data. It also features digital filtering to reduce noise. Finally, AGILENT 7890A features an alphanumeric keypad and a monitor for controlling the instrument and monitoring all processes. The 80-character in-line alphanumeric keypad provides user with the ability to select columns, store data and run tests, experiment analyses, and review results. The monitor provides a visual display of the status of the instrument. 7890A is capable of delivering reliable, consistent and precise performance, with low detection limits for various compounds. In conclusion, HEWLETT-PACKARD 7890A is a GC spectrometer that offers users high-performance results for determining components in a mixture.
