Analytical Instrument Management offers quality custom configured, refurbished Agilent 6890N Gas Chromatograph Systems. All of our systems are completely refurbished, rigorously tested and guaranteed to meet manufactures specifications. Our customers are supplied with a comprehensive data report detailing the instrument performance prior to shipping.

Agilent 6890N GC systems are known for their reliability, ruggedness, and long life. The Agilent 6890N is a state-of-the art gas chromatograph that provides superior performance for all applications. Key to its performance is the use of advanced electronic pneumatic control (EPC) modules and high performance temperature control. Each EPC unit is optimized for its intended use with a specific inlet and detector option. Temperature control of the 6890N oven allows for fast and precise temperature ramping. Overall thermal performance provides optimal chromatography including peak symmetry, retention time repeatability, and retention index accuracy. The combination of precise pneumatic control and accurate temperature control leads to outstanding retention time repeatability, the basis for all chromatographic measurement.

Agilent Nitrogen Phosphorous Detector (NPD)

• Optimized selectivity and sensitivity for nitrogen- and phosphorus-containing compounds

• NPD with Blos bead offers robust operation, better stability and longer bead lifetime

• Bead is digitally set from the keyboard and is auto-correcting

The Agilent 6890 nitrogen–phosphorus detector (NPD) is a type of detector commonly used with gas chromatography, in which thermal energy is used to ionize an analyte. With this method, nitrogen and phosphorus can be selectively detected with a sensitivity that is 104 times greater than that for carbon. NP-Mode: A concentration of hydrogen gas is used such that it is just below the minimum required for ignition. A rubidium or cesium bead, which is mounted over the nozzle, ignites the hydrogen (by acting catalytically), and forms a cold plasma. Excitation of the alkali metal results in ejection of electrons, which in turn are detected as a current flow between an anode and cathode in the chamber. As nitrogen or phosphorus analytes exit the column, they cause a reduction in the work function of the metal bead, resulting in an increase in current. Since the alkali metal bead is consumed over time, it must be replaced regularly.
