I'm not into quartz
haha. you are slightly smarter than I thought. However... seriously??? la-icp-ms for quartz only? this is what you got from 5min googling the word "la-icp-ms" and hit the wikipedia button. There is only one mineral included in the wiki page. Guess what it is? QUARTZ!!!
In my knowledge this machine is used by some top of the line lab to determine alexandrite's origin for russian alex and be treatment.
Quartz... lol
I bet smaller lab require to buy the overly expensive la-icp-ms machine, coz I bet they receive tons of quartz everyday.
Here's some scientific data you won't find anywhere
The reason labs have LIBS is for Beryl you don't need the plasma tech for beryl, but in quartz the plasma is better.
Now the 'top labs' have already moved into SIMS.
I think the costs are like this
LIBS for beryl ruby detection around 50K or so
Plasma units for beryl and syn quartz is 300K or so
SIMS the real state of the art tech is 750K to 1M
So if you really want to see what labs are 'up to date' ask if they use SIMS yet.
I doubt many do.
Beryl is a problem and pretty much every 'lab' doing ruby certs has at least a LIBS
Now a major issue with beryl is that in Sapphires it has been found in both 'natural' and infused. So the more you start to look for treatments the more you see some stuff has been there all along. LOL
I think most labs are actually using the higher end tech from nearby universities and such and the whole problem with the Laser Plasma analysis is it destroys the sample since you end up with laser holes in the sample.
The safest analysis is still high powered microscopes with great lighting.
LIBS shouldn't damage samples sub LA-PL can.
I haven't heard of damage from SIMS yet but that tech is usually only in high end universities and or major research labs not gem labs.
