Safety ring for double open-ended sample holder cell for spectroscopic analysis

A sample holder system for a sample material for X-ray spectroscopic analysis, comprising, in combination,

• cell means for containing the sample material and having first and second rims defining opposed first and second open faces, respectively,
• a first ring mounted to said cell means at said first open face,
• an analytic film secured to said cell means by said first ring across said first open face,
• a second ring mounted to said cell means at said second open face, said second ring including a continuous ring wall extending outwardly from said second rim and perpendicular to said second open face, and
• a protective film secured to said cell means by said second ring across said second open face,
• said continuous ring wall and said protective film defining a compartment adjoining said second open face,
• said compartment arranged to receive particles passed from said cell means through said protective film due to the heating of said sample material by X-rays.
