Analytical instrument - CRDS isotope monitor - an instrument for automated monitoring of environmental levels of methane. Both mixing ratio and stable carbon isotope composition must be measured. The instrument must be field deployable and work without cryogens and generate data with a time constant <180 seconds. It will largely be based on a climate observatory in the tropics and seldom be re-located. We now request information on the state of the art with respect to these kinds of measurements.

2024-03-08   Gasvarnare med tillhörande utrustning och service (Roslagsvatten)
Upphandlingen omfattar köp av gasvarnare med tillhörande kalibrerings- och bumpstation, inklusive kalibreringsgaser, för eget utförande av kalibrering och bumptester. Även service av både gasvarnare och tillhörande utrustning, enligt tillverkarens rekommendationer ingår i upphandlingen som en option. Visa upphandlingen »
2016-06-30   Isotope Measuring Instrument (Stockholms universitet)
The purpose of the equipment is to measure the mixing ratio and carbon/hydrogen isotope composition of atmospheric methane at remote field stations and in flask samples as part of our research program. The equipment will also be used to analyse head-space gas that has been equilibrated with water samples. Visa upphandlingen »
