I suppose you could crush it up... The XRF looks at the very surface of whatever the laser hits. So I'm not sure crushing a sample would be getting you anywhere. Why would you crush it Stillbilly? -

There are guys all over that do testing like this but they don't usually advertise to the public. Contacting their customers are the best way to contact them. Call a hazardous materials remediation contractor. Anybody that removes asbestos, lead paint, spills, etc. Every one of those outfits contract with a materials testing lab that has XRF capability. Any architectural or engineering firm has a phone number to call to test for lead paint or tiles. That is the number you want. -

Some jewelers, prospecting stores, pawn shops... I know a guy-5minutes and 10$ cash later... Have you a small sample you could crush to powder in a mortar? Put the resulting "rock" flour in a ziplock bag and it's ready to go. -

There are materials testing outfits all over. Ask anyone involved in construction and they can point you to someone that can perform an XRF analysis for you. It generally will cost about $15 if you take the sample to them. If you don't require a written report most guys will shoot your rock for free. It only takes about five seconds. Keep in mind it only analyzes a tiny spot that the laser hits. So on a specimen like a low iron chondrite you won't get an accurate assessment unless you shoot the specimen a few times and make sure some metal gets under that tiny spot the machine is "seeing".
