Use of miniRUEDI Instruments in Air/Water Exchange Studies in Small Streams

In their recent paper “In-situ mass spectrometry improves the estimation of stream reaeration from gas-tracer tests“, Julia Knapp and her colleagues at Uni Tübingen and Eawag used two miniRUEDI instruments to study air/water exchange in small streams.

Highlights:

  • Determination of gas-exchange rates in streams from gas-tracer testsQuantification of gas tracers using a portable gas-equilibrium mass spectrometer
  • Reliable estimation of reaeration rates from krypton and propane injections
  • In-situ analysis avoids gas loss and improves the determination of reaeration rates
