Hi all,

I was just wondering if anyone has run any of the limestone reference materials that are now offered by Elemental Microanalysis. They offer six different limestone samples with the following compositions:

2.93%C 0.02%S

5.87%C 0.029%S

7%C 0.145%S

11.7%C 0.22%S

11.97%C 0.044%S

11.72%C 0.418%S

If you have run any of those on either the gas bench or EA, can you please let me know what the approximate delta values are for those materials? Thank you very much!
