Agilent Technologies Heart-Cutting Capability for the 6890 Gas Chromatograph (GC) is a full implementation of the Dean’s switching technology. This technology ensures that there are no pressure or flow fluctuations in any of the switch paths.
This document describes the Agilent Technologies Heart-Cutting Capability for the 6890 Gas Chromatograph, featuring a full implementation of Dean's switching technology. The system ensures no pressure or flow fluctuations by continually sweeping all branches with carrier gas throughout the analytical process.
The hardware includes Sulfinert-treated metal surfaces to minimize active sites and utilizes Agilent Electronic Pressure Control for reproducible retention times. It is designed for applications such as analyzing oxygenates in gasoline, thiophene in benzene, and chemical warfare agents.
