ION CHROMATOGRAPHY ANALYSIS:
Anion Suite: Fluoride, Acetate, Formate, Chloride, Nitrite Nitrogen, Bromide, Nitrate Nitrogen, Phosphate Phosphorous, Sulfate, Oxalate, Thiosulfate
Note: Not all anion species may be present and special sample handling is required for the quantitative determination of acetate, formate, and thiosulfate.
$28.75 per sample.
Minimum sample size is 5 ml without dilution.
INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY (ICP-OES):
Water Major Element Suite: Li, Na, Mg, Al, Si, P, Ca, Mn, Fe, Sr, Ba (Y internal standard).
$28.75 per sample which includes the average of 5 replicate measurements and necessary dilutions.
Minimum sample size is 3 ml without dilution.
Rock Major Oxide Element Suite: Na2O, MgO, Al2O3, SiO2, P2O5, K2O, CaO, TiO2, MnO, Fe2O3, SrO, BaO (Y internal standard).
$40.25 per sample which includes the average of 5 replicate measurements, CEM microwave digestion, Loss on Ignition (LOI) if requested.
Recommended sample size is 150 mg (50 mg minimum) and powder must be 150 micron or less and homogenous.
Custom Element Suites: Any combination of 1 - 15 elements analyzed at the same time (Y internal standard).
$28.75 per sample which includes the average of 5 replicate measurements and necessary dilutions.
Minimum sample size is 3 ml without dilution.
INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY (ICP-MS):
Rock Trace Element Suite: Li, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Nb, Mo, Ba, Ta, Pb, Th, U, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu
$46.00 per sample if included with the Rock Major Oxide Element Suite that is charged at $40.25 per sample.
$57.50 per sample if analyzed alone (includes the CEM microwave digestion sample prep).
Recommended sample size is 150 mg (50 mg minimum) and powder must be 150 micron or less and homogenous.
Water Trace Element Suite: Li, Al, P, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, Cs, Ba, Tl, Pb, U (Indium internal standard)
$28.75 per sample which includes the average of 5 replicate measurements.
Minimum sample size is 3 ml without dilution.
Sample Preparation: Any solid sample that requires an acid dissolution or digestion, will be charged $6.25 per sample in addition to the cost of the element suite. Rock or Silicate analyses, or any other type of sample preparation requiring a CEM microwave digestion will cost $11.50 per sample in addition to the cost of the element suite(s).
