Testing % of Nylon In Film

Hi all, I am tasked to find a piece of equipment to test the percentage of Nylon in film.  Currently we are using a microscope which is a very painful, cumbersome, time consuming, and not very accurate method of finding the percentage of Nylon in the film.  Would anyone here have a recommendation on what I should research to purchase?  

What are typical compositions of your films? Are they laminated multilayers? 

If the film has a mix/co-polymer monolayer structure, a sophisticated method is needed such as spectroscopy, gel chromatography, calorimetry; even microscopy requires electronic types. Sending samples to an external labo looks like a good idea when the tests don't have to be frequent.

Hello beautiophile,

We do multi-layer (5 to 7) films.  We are needing to test Nylon layer % frequently so sending it out to an outside lab is not practical for us as results are needed in real time. 

Hi All, 

Just checking in to see if anyone had any additional suggestions?
