Measurement of air samples for isotopic composition of CΟ (δ13C, δ18O) at Utrecht University.

Measurement of gas samples for clumped isotopic composition of CH4 (Δ13CDH3 and ΔCD2H2) at Utrecht University.
These measurements can be used for determining methane formation temperatures and non-thermodynamic equilibrium processes. 
Samples should be provided in suitable flasks. The concentration needed is typically > 5%, and it may be possible to analyze samples with CH4 as low as 0.5 %, upon discussion. One analysis needs at least 5 ml STP of pure methane. The samples should always be discussed in advance. 

TIME CONSTRAINTS: Possible long waiting times

Measurement of air samples and calibration of cylinders for isotopic composition of CH4 (δ13C and δD) at Utrecht University.
These measurements can be used for source attribution and isotope budgeting. 
Atmospheric samples should be provided in clean glass or metal flasks, suitable bags or cylinders in which CH4 is stable. 
Samples from other media (water, sediments, etc.) can be analyzed as well. Specification of the sample containers and expected concentrations is beneficial.

Specific experiments performed by using the available equipment at AGORA, combined with external equipment if needed. 
For example: use of polar nephelometer to study controlled ambient particles.
The service includes:
-      Administrative support to comply with internal procedures for accessing facilities (physical).
-      Administrative and technical support for providing a workspace for visitors:  desk space with computer and internet access, meeting rooms, kitchen and lunch room (physical).

Custom experiments on aerosol chemistry and physics: ChAMBRe is a multi-purpouse facility connected to a laboratory fully equipped for aerosol sampling and characterization. 
Specific experiments/tests can be organized with the support of the ChAMBRe teams.
