Metrohm 881 Compact Pro

Measurement of anions in eluates are performed on a Metrohm ion chromatograph (IC) model 881 Compact IC Pro with a Metrosep A Supp 5 column.  The column separates each anion based on its reaction to the column at a given time.  The conductivity detector measures the anion concentration from parts-per-billion to percentage range.  Analysis using a seven-anion standard is made following EPA Method 9056A.

The following anions can be measured:

Chloride (Cl^–)
Fluorine (F^–)
Nitrite (NO₂^–)
Nitrate (NO₃^–)
Phosphate (PO₄^–)
Sulfate (SO₄^–)
Bromide (Br^–)

The IC is a staff-run instrument with pricing based on a per-sample charge. All sample submissions are handled via MDERFH’s iLab Core.
