Carbon monoxide in engineering database

Hi

Has any body access to temperature dependent thermal conductivity data on carbon monoxide? Or how to calculate it?

Most data for carbon dioxide I've been able to extract from the databases below. But I'm stuck at the thermal conductivity of the gas for more then one temperature. Any ideas?
