Do you know an alternative to (very expensive) nafion gas dryers like the Permapure pd-200t-12 mps? How would you dry CO2/CH4 in QCL/CRDS?

I'm on a field trip in Canada at the moment and my drying unit shows signs of a leaking nafion-membrane. I checked and replaced o-rings already and for now exclude any other source of error....
