I am looking to condense gases from a reactor and had previously made use of a PIDTECH reactor which comes equipped with a peltier cell with level control for collection of condensate. I'm working at low flow rates so typical condensers will not allow easy collection of condensates.
Here I think

Thanks @Luca Patauner. I saw this one but not sure i will be able to adapt it for gas or get as effective cooling as when used for liquid. But will try it out and see
You could try having a look at the RS Amidata catalog (http://uk.rs-online.com/web/c/hvac-fans-thermal-management/electronics-heating-cooling/peltier-modules/?searchTerm=peltier). Selecting the appropriate cell requires a bit of reading carefully the tech. specs. of the articles and some rough estimations/calculations of the heat flux, DeltaT, etc. In principle it should not be difficult to do. Anyhow, if you are working at really low gas flows a coil condenser similar to cold traps used in other common lab equipments could also work to collect condensables from gases. Good luck!
