[QUOTE="Hawkear, post: 668404, member: 4728"] Shouldn't make any difference as XRF is a process that works at the atomic level and would be independent of particle size. In fact larger particle size could be a problem if irregularly spaced and sampling measurements would need to be done over multiple sites to ensure that irregularly spaced particles are accurately represented in an overall average. XRF machines are manufactured to various levels of accuracy and speciality for the elements to be detected. Laboratory based XRF machines such as used by institutions such as universities, museums etc. can have much higher accuracy levels than the smaller and less expensive handheld XRFs. [/QUOTE]
