They both look the same to an ICP.
Did you copy that from somewhere on the Internet?
Did I copy that from the internet lol. I seen that on bitog before actually. Where did you get your information on UOA's if not from the internet? I post my UOA's to learn but a lot of people pick apart some things that are minor. Most also seem to think they know more than blackstone. I am pretty new to reading UOA's so I am open to learn what I can.
I'm not sure what you are getting at exactly, the comment wasn't in response to you. Although the post contained correct information it doesn't directly apply to an elemental analysis that's part of a UOA.
It's not a minor point. The plasma in an ICP (or even an AA machine, which I used in college) will decompose nearly any chemical compound and you have no way to trace it back to any specific source. It's like hammering a vase into sand, where you can say it was "glass" but you have no idea what it looked like before it was crushed. That's why if you wish to trace something in this type of test the sources have to be tagged, generally with radioactive isotopes. Otherwise you don't know where the (silicon in this instance) is coming from.
The exception is when you only have one source, but here you have more than one.
