Comparison of instruments measuring LWC with a fixed European ACTRIS reference instrument, short report and certificate

TIME CONSTRAINTS: Yearly

SERVICE STATUS: In implementation, starting in 2023/24

The service consists of:
- Provision of data from simulation chamber experiments,
- possibility to perform several day-long experiments in the simulation chamber, 
- technical service to use own instruments,
- training for planning, evaluation and interpretation of experiments. 

Availability period: Typically between April and September (photo-chemistry experiments)

Estimated duration: None, although access has to be coordinated with other activities in laboratory

QUAREC can be used to test instruments developed for use in air quality measurements: 
- testing and comparison of instruments and methods
- scientific and technical training.  

Estimated duration: None, but the request of access should be sent at least 2 months in advance.

The QUAREC facility (the simulation chamber and the analytical instruments) allows investigating:
-      homogeneous gas-phase reaction systems (determination of rate coefficients and products formation for the reactions of OH, NO3 halogens and ozone with VOCs)
-      formation of airborne particulates in homogeneous gas-phase reaction systems.

Estimated duration: None, but the request of access should be sent at least 2 months in advance.
