Aurosa 4000 zero air - drying or compressor?

Post by Elsasser »

Dear all,

we are planning to run an Aurora 4000 and have a question regarding the zero air. Do we need to use the zero air from the sampling line so that we have the same air as the aerosol air and if yes, do we have to use also a denuder to dry the zero air as we do it for the sampling line? Or is it also possible to use the zero air e.g. from a compressor?

Thanks
Michael
