PEEK PREVIEW: AutoSampler for High-THROUGHPUT Gas Flux MeasurEments
VSI GF-500 HT Gas Flux Autosampler. The exchange of gaseous compounds between the atmosphere and different types of surfaces has received increasing interest, not the least in connection with studies of large-scale pollution problems, climate change and biogeochemical cycles.
The VSI GS-500 autosampler allows for a high-throughput surveying of emissions of your trace gases of interest. A common application would be the monitoring of soil samples or microcosms under controlled laboratory settings (climate chamber).
As the system allows for closed-chamber measurements but the samples are incubated within one environment, the standardisation of environmental parameters is beyond commonly applies closed chamber/flask measurements.
We currently expect the first system to be available for customers in early 2021 and all options until 2022. Get in contact if you are interested in early teasing and hands-on!
VSI GF 500 HT Gas Flux Autosampler - Features
Key features:
- 10 large sample spots incubated under the same environmental conditions, allowing to hold samples of different sizes
- Pre-measurement chamber flushing with outside air
- Measurements steps can be set freely, allowing for 24/7 measurements
- An integrated scale allows to record (potential) water loss by evaporation as a key co-variate of soil respiration measurements
- Integrated recording and operation with common IRGAs (as available)
- Integrated climate chamber control (for now BINDER models only)
Future autosampler models will also feature:
- Glas chamber to allow to measure ecosystem respiration with small plants, mosses etc. under ongoing light
- Teflon chamber to allow to measure volatiles
- Additional chamber flushing with bottled gases (e.g. synthetic air)
- Automatic irrigation system
