Standard XRF cups are composed of three parts: the sample cup, the sample film, and a retainer ring. The sample is placed in the cup and then the film is placed on top with the retainer ring being pushed down to hold it in place.
Accucells are essentially smaller, pre-assembled XRF cups. The sample is inserted through a small hole on top of the cup. These do not need to be vented.
No, reusing sample cups and film causes contamination issues that will lead to incorrect results.
For MWDXRF analyzers such as Sindie, Clora, Signal, and Phoebe it is recommended to vent all samples, including non-volatile samples. Venting on Petra analyzers is not needed but allowed if your standard operating procedure calls for it. If venting Petra samples, make sure to vent cup in 12 o’clock position (not in center) to prevent leaking samples.
When using the standard XRF sample cups, the proper procedure is to “vent” the sample. This means to poke a hole on the back of the cup, allowing any vapors to leave the sample cup. Trapped vapors can cause bowing in the sample film, which can lead to irregular results.
