Description

Frequent collection and ICP-MS analysis of river water samples to detect thorium concentration excursions as indicators of bedrock fracture processes. Samples collected up to daily frequency and analyzed for ultra-trace thorium concentrations.

Typical Equipment

sample bottles
0.45 μm polyethersulfone syringe filters
inductively coupled plasma mass spectrometer (ICP-MS)

Output Measurements

thorium concentrations
beryllium concentrations
arsenic concentrations
discharge measurements
