Total Elements-Nitric Acid Digestion

Plant: B, Ca, Cu, Fe, Mg, Mn, P, K, Na, S, Zn
[also available: Al, Ba, Cd, Cr, Co, Pb, Mo, Ni, V]

Summary

This method quantitatively determines the concentration of B, Ca, Cu, Fe, Mg, Mn, P, K, Na, S and Zn and a variety of other elements utilizing a nitric acid/hydrogen peroxide microwave digestion and determination by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The methodology utilizes a closed vessel digestion/dissolution of the sample. The method has detection limits ranging from 0.5 ppm to 0.01 %.

Element MDL
B 1.0 ppm
Ca 0.010 %
Cu 0.5 ppm
Fe 1.0 ppm
Mg 0.010 %
Mn 1.0 ppm
P 0.010 %
K 0.01 %
Na 1 ppm
S 10 ppm
Zn 1.0 pp


Sample amount requested:   5 g for any or all of the above
