I'd like to automate a continuous flow EA/IRMS system to have a liquid nitrogen trap lower into a 
dewar and then lift out at the right time.  We'd like to basically build this simple component of a 
precon or a gas bench without having to buy a whole precon or gas bench.  Has anyone had 
experience building that type of setup?

Thanks
