Marty,
excellently described.
Is there actually a "minimum" or even "maximum" number of "XRF-shots" (I apologize for not knowing the correct term) per sample to even get an average value of a specific element content, or is there just "1" "shot" needed or allowed, respectively?
I mean, in worst case one could be tempted to measure just long enough to finally achieve the "correct" value.
Thanks in advance for a short reply and best regards,
Stephan
