Answer:Two gaskets are supplied per package.
Answer:Shimadzu lists the set for several SPD UV/PDA detector families, including SPD-20A/20AV and SPD-40; verify the exact cell configuration.
Answer:Replace them during the prescribed cell disassembly or when a worn or deformed gasket compromises liquid tightness.
Shimadzu flow cell gaskets maintain a liquid-tight seal at the optical flow cell interfaces of compatible HPLC UV and photodiode-array detectors. The replacement gasket set is listed for multiple SPD detector families, including SPD-20A/20AV, selected SPD-10-series units, SPD-40 and compatible integrated LC instrument flow cells. The package contains two gaskets. Proper gasket integrity helps prevent solvent leakage around the cell windows and supports stable optical measurements after cell cleaning or reassembly. During servicing, shut off mobile-phase flow and relieve pressure, then disassemble the optical cell using the specified detector service procedure. Inspect optical windows and gasket-contact surfaces for scratches, residues or deformation. Fit new gaskets in the prescribed orientation and avoid pinching them while reassembling the cell. Flush the cell with a compatible solvent, check for leakage and verify baseline response before analytical use. A gasket replacement is not a substitute for cleaning damaged windows or correcting an incompatible detector cell assembly.
