Shimadzu, 206-77703-91, 气体流通池池架MVU HOLDER ASSY，用于AA-6880

The Shimadzu gas flow cell holder supports a separate gas flow cell used with a mercury vaporizer unit in an atomic absorption spectroscopy workflow. The holder positions the cell in the optical path so vapor-phase mercury measurements can be performed with the appropriate vapor-generation accessory. It is a mounting component rather than a gas flow cell, detector or complete mercury analysis system. Stable mechanical positioning matters because misalignment can reduce optical signal quality and complicate reproducibility. Inspect the holder and cell seating surfaces before assembly, and ensure the gas connections and measurement accessories are installed in the correct compatible instrument configuration. Service personnel should confirm the vaporizer, spectrometer model and optical cell fit together before selecting replacement hardware. This component is relevant to maintenance of mercury vapor measurement setups and should not be substituted for the optical cell itself.
