composition of gas diffusion membrane

We have been using the FS3100 cynide analyzers in our lab since 2006.  In the past few years I have noticed a change in the look of the 25mm gas diffusion membrane.  It appears to be more "shiny" than before.  Are you aware of a material change for this product?

Hi Erika

Are you using the polypropylene (A001520) or the teflon (A002040)? Where are you getting your supplies?

We are purchasing from OI .  Theirs are poly now but I am wondering if we need the Teflon for our set up.  The ones OI sent in the "old days"  Ihave spoken with Kevin at EZkem and sent him an email to forward to you with more information.  If you could help it would be very much appreciated!
