High Resolution Auto Sampler (HiRAS)

Automated sampling even at remote stations

The automated sampler in its compact form allows self-sufficient sampling over long periods of time even in remote areas with limited access.  

  •  Program your sampling protocol by time interval, volume, event-driven, or combined
  •  Rack of up to 165 samples gives you an extensive database of high-resolution precipitation events or for very long measurement series
  •  High resolution: Up to 2 mm / 5 min

Optimized for stable isotopes

  • Sampling and storage are performed in individually hosed disposable syringes without air exchange, allowing the samples to be used for stable isotope analysis, as well as other chemical analyses.
  • Valid results: Sampling without cross-contamination, absolutely gas-tight.
  • Optimized in long-term tests of the GFZ (Nepal, Zugspitze, Potsdam).
  • Isotope stability (18O, 2H) min. 3 months, up to 50°C.

Remote access

  • In regions with GSM network, the Android-based mobile app gives you access to the device at any time.
  • This enables, e.g. targeted sampling of events.
  • With intuitive user interface to change parameters, testing of valves, starting, adjusting, ending the sampling protocol, live check of values.

Longterm monitoring

  • Low energy consumption
  • Self-sufficient, flexible energy supply
  • Battery, Solar panel or mains operation

Rugged and compact

  • Stable Pelicase for easy transport, 3D-printed rack, low weight
  • Reliable
  • Wear-free filling, gas-tight sample storage

HiRAS - the multitalent

The prototype of HiRAS was developed for stable water isotope sampling at weather stations. Together with you, we can adapt and optimize HiRAS for your application, i.e. for:

  • routine measurements for immission monitoring
  • tracer tests, determination of breakthrough curves of harmful substances, regular analyses during production processes, process optimization
  • hazards monitoring (dispersion of hazardous gases or liquids in air, groundwater, rivers and more)
  • remediation of contaminated sites, landfills and stockpiles
