Yeah, I gathered that from reading the thread. It's good SRM.

I can confirm that Arsenic can and does show up as Iridium on an XRF.

Mee too. Arsenic read as PGMs (in my case solid chunk of native arsenic with Ag content of 1 %) - Olympus Vanta read mostly osmium and iridium, but it vary with spot and angle.
It was shot on Precious Metals mode of course. On geochem mode it did OK job, reading arsenic and silver, alongside with half of the periodic table

Just for confirmation that an XRF can & will lie to you & tell you have PGMs when in fact what you have is arsenic

What's wrong with a little arsenic? Actually... Maybe that's what's wrong with me...
