Series 1600
SLIT-VENTED SAMPLE CUP CAPS
FOR 1500 SERIES XRF SAMPLE CUPS
Sample Cup Caps are designed for use with the corresponding diameter size of catalog numbers 1530 and 1540 sample cups. When assembled, a series of physical barriers is established that form a path of travel to four venting slits. In evacuated conditions, non-volatile liquids and powdered sample particles are unable to continue the complete tortuous travel path impeded by barriers. Pressure equilibrium is therefore established between the interior sample cup and sample chamber while the sample material remains confined within the sample cup. Thin-film sample support windows remain taut resulting in flat sample support planes.
The interior of the Sample Cup Cap integrates a circular trough formed by the outer wall and a raised ridge within the Cap. A hollow is similarly formed within the center of the cup that helps in particle deflection back into the sample cup.
When attached to a corresponding diameter size sample cup, the Cell Neck of the sample cup fits into the trough of the Sample Cup Cap. The combination of the two part assembly creates two separate circular troughs separated from each other by the Cell Neck and raised ridge of the Sample Cup Cap. The separation between the two formed ridges, or baffles, suffices for evacuation of the sample cup through the four integrated vent slits but presents difficulty for powdered sample particles to freely travel owing to the baffles and tortuous path of travel.
Affix a thin-film sample support window to the Cell neck opposite the flanged end. Insert sample substance. Attach Sample Cup Cap to the open end of the Cell with the flange around the outside diameter.
