Make your own polystyrene film standard for IR spec use.

Here's the spectrum taken by a Perkin Elmer model 700 IR spec in 1968. I have a copy of another polystyrene spectrum with better resolution that I got from the library.

The first link stopped working for some reason. It was about making your own polystyrene film standard for IR specs. Just mix 1 g of polystyrene foam with about 4-5 ml of acetone or toluene, pour on a glass plate and let dry.
Looks like the link works sometimes and other times it doesn't, so I uploaded it here. http://www.geocities.com/dritte123/363-1

I found out polystyrene foam or what I had doesn't dissolve in acetone, but will dissolve in toluene. I made some polystyrene film by putting a solution of polystyrene in toluene on top of water in a pyrex dish and let it evaporate. It came out clear like Saran wrap except the edges of the film are thicker than the center.
