Planned laboratory equipment

Main grid power will be brought to the site by the electricity network in March 2024.

The following is a list of the planned analysers for the two instrument rooms.

1. Picarro G2401 (CH4, CO2, CO concentrations) with inline drying/sampling unit. From NPL and currently under testing ready for deployment.

Analyser assembled and tested at NPL ready for deployment. On the left a sampling unit consisting of a selector valve (to switch between reference gases and air sample) and a drying membrane to reduce water content. On the right a Picarro CRDS detector for measurement of carbon dioxide and methane.

 

2. Picarro G5310 (N2O, CO) - expected delivery to NPL in February 2024.

3. Aerodyne dual laser spectrometer for methane isotopes - expected delivery to NPL in 2024. This instrument is capable of very high precision measurements of 13C/12C and D/H following setup by Rennick et al., 2021

4. Medusa GC-MS (gas chromatograph mass spectrometer) for halocarbon, SF6 and NF3 concentrations, from the University of Bristol. See Miller et al., 2008 and Arnold et al., 2012

5. GC-PID (gas chromatograph photo ionisation detector) for H2 concentration, currently being built and tested by the University of Bristol.
