Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A #293627319 for sale

HP/AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A Gas Chromatograph is an instrument that allows for the separation, analysis and identification of a multitude of volatile and semi-volatile substances. It utilizes a mass-less source in combination with a high-resolution combination ion mobility spectrometer and electrochemical detector to enable chemical detection, analysis and/or identification of volatilizable and semi-volatile organic compounds. HP 7890A is a mid-ranged GC instrument; it is capable of both qualitative and quantitative analysis with an ability to detect molecules as small as 0.1ng/mL. The automatic feature allows the GC instrument to operate with little system maintenance or manual involvement which makes it ideal for laboratories with limited resources. The instrument operates on a modular design, meaning that it is highly customizable to the chemist's needs. AGILENT 7890A comes with pre-installed options for temperature control, detectors andcolumn size, as well as supported software. The GC column is a capillary quartz-lined column that separates molecules during the gas chromatographic process. The separation occurs when a sample is injected into the system and heated, causing molecules to move more quickly or slowly based on their size, weight and structure. These molecules then reach the detector, allowing the chemist to analyze the spectrum. 7890A can also be designed with an ion mobility spectrometer, which helps to identify and differentiate between compounds. The 7414A detector utilizes an electric field to sort out compounds that don't follow the GC separation. Additionally, the electrochemical detector measures peak areas of an eluted sample when a voltage is applied for qualitative analysis. HEWLETT-PACKARD 7890A is easy to use and its performance is comparable to that of the lower-end models in its class. Furthermore, the superior resolution, selectivity and sensitivity of this instrument enables laboratories to produce more accurate results than with the other instruments in its class. This makes KEYSIGHT 7890A a great choice for anyone looking for a mature, reliable GC instrument.
