Sample holder for spectroscopic analysis and method for mounting film to sample holder

摘要

A sample holder for positioning and locking film for sample materials for spectroscopic analysis comprising a holder body having a cylindrical outer wall forming a cell adapted to contain the sample material and a ring member for biasedly pressing the film skirt against the cylindrical outer wall of the holder body in a first locking position. A locking bead around the ring member presses the film skirt into a locking groove around the cylindrical wall of the holder body in a second locking position. An optional third locking position is attained by a second locking bead around the biasable ring member pressing the film skirt into a second locking groove around the holder body. A method of assembling the film with the holder body and the ring member is also described.
