Total Elements (Includes Phosphorus, Zinc, Manganese, Iron, Copper, Molybdenum, Cadmium, Chromium, Lead And Nickel)

Soil Totals: Zn, Mn, Fe, Cu, Cd, Cr, Pb, Ni, P, Mo


This method determines the concentration of Cu, Cd, Cr, Fe, Mn, Ni, P, Pb, Zn and additional elements as requested utilizing a nitric acid/hydrogen peroxide closed vessel microwave digestion.  Analysis is by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES).  Typical method detection limits are 1 mg/kg for all elements except cadmium (0.1 mg/kg) and phosphorus (0.001%). Sample amount requested is 3 g powdered or finely ground sample.
