8300 icp aes

Filtrate was collected and analyzed for major ion concentrations through ion chromatography (IC) and inductively coupled plasma atomic emission spectroscopy (ICP-AES) spectroscopy. IC analyses were run on a Dionex ICS-900 IC system, while ICP-AES was performed on a PerkinElmer 8300 ICP-AES. ICP samples were acidified with 3 to 5 drops of 10% nitric acid with a total volume of 12 ml for sample submission. Additional fluid collected from boreholes was run on a Picarro water isotope analyzer (D/H and ¹⁸O/¹⁶O) with cavity ring down spectroscopy (Picarro, Inc., Santa Clara, CA, USA) in order to determine source water variability of the borehole fluids.

Filtrate from melted snow (0.45-μm pore size) was subsampled to two 15 mL aliquots for ion chromatography (IC; major anions) and inductively coupled plasma atomic emission spectrometry (ICP-AES; major cations) analysis. ICP-AES samples were acidified with three drops of trace metal grade 10% nitric acid. IC analysis was performed on a Dionex ICS-900 IC system running an AG14A-5 μm RFIC (3 × 30 mm) guard column and an AS14A-5 μm RFIC (3 × 150 mm) column, while ICP-AES was performed on a Perkin–Elmer 8300 ICP-AES.
