Appreciable scientific community:
Is there a digestion methodology to obtain the major elements of igneous rocks using an ICP-AES?
I am currently doing my thesis and my university has an ICP-AES Icap7000 Thermo. We also have a microwave digestion system model MARS and standards of rocks from USGS.
Previously, acid digestion was realized with the microwave to obtain major elements (SiO2, Al2O3, etc) of igneous rocks with the ICP-AES. But, I do not know if the methodology is good or if there is a better for acid digestion
If anyone could provide me with information or references. I would be very thankful
Greetings from Mexico
above are well developed instrumental technologies Sufficient literature and a large number of publications are already available
There are many studies about that and most of them proved that XRF (X-ray fluorescence) is a more recommended and precise technique for major oxides/ elements than ICP-AES. These studies showed that there are big differences between those two techniques in the case of measuring majors. XRF is also used to determine the traces, however, ICP-AES is especially more appropriate for elements lighter than Na (sodium) and this is not available in XRF. Finally, XRF is more recommended in your case.
