Chemistry test list

Inorganic Chemistry – Soil/plant/water/other

  • ICP scan of twenty elements  including:
    • Aluminium, arsenic, boron, calcium, cadmium, cobalt, chromium, copper, iron, magnesium, molybdenum, sodium, nickel, phosphorus, lead, sulfur, selenium & zinc.
    • If not all elements are required testing can be for individual elements or a number of selected elements.
    • Alternatively elements can be grouped into metals ( Al, As, Cd, Cr, Cu, Ni, Pb, Se Zn), nutrients ( B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Zn) or cations  (Ca, Mn, Na, K).
  • Total carbon and/or total  nitrogen by DUMAS combustion (LECO)
  • Anions: Cl, NH4, NO2 , NO3, PO4, SO4
  • Plant nitrate
