Automated sampling even at remote stations
The automated sampler in the compact form enables self-sufficient sampling of long series of precipitation even in remote stations. The sampling and storage takes place without atmospheric exchange and enables the use of the samples for various chemical, but also isotope analyses.
Program your sampling protocol based on events, by volume, or optionally by time interval, or a combination of both criteria.
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

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
HiRAS-Autosampler (Standard Model) includes:
Rain collector 300 mm, with bird deterrent ringand leaf catcher for direct attachment to the autosampler
Precipitation water buffer tank with volume detection
Filling of disposable syringes via valve hub and FEP capillaries, with largely atmospheric seal
Autosampler is delivered fully assembled with disposable syringes and FEP capillaries
Mobile App for Android
Anchorable and height-adjustable stand for HiRAS
1x base plate with 4x leg mounts suitable for the Pelicase incl. 4x knurled screws for mounting on the Pelicase
4x legs individually adjustable in height between 55 and 95 cm via slides with hand toggle
8x knurled screws for attaching the legs to the base plate leg sockets
4x ground screws for anchoring the legs
Material: aluminum and stainless steel
tool-free assembly
