FTIR IR Liquid Cells - Sandwich Cells
A sandwich cell consists of two (2) windows separated by a lead spacer that is amalgamated to the windows with mercury. The mercury lead amalgam is impervious to solvents and to virtually any sample. The spacer and windows form a sealed liquid sample compartment. In the case of the SL-2 configuration, the sandwich cell is also amalgamated to an aluminum front plate containing luer-lok syringe filling ports.
Sandwich cells can be used to recondition sealed cells, to have backup or supplemental sealed cells of different pathlengths, or in a demountable cell. You will find sandwich cells that will fit most sealed and demountable cell holders that have been made in the last 25 years.
