Agilent 6890A/G1530A With Headspace The Agilent 6890N is a state-of-theart 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.A full array of traditional gas sampling and column switching valves are available. A new high performance inert pneumatic switching manifold is available for a number of advanced chromatographic applications (2-D heart cutting, detector splitting, etc).
