Which FTIR preparation for polystyrene?

  1. Aug 2, 2012 #1
    If I have some polystyrene and want to analyze it using FTIR for trace elements, what type of sample preparation should I look into? If I were to use a liquid sample preparation, I wouldn't be able to use say, toluene, because the two structures are similar, correct (aromatic)? On the other hand, if I were to use a solid sample preparation by making the KBr disk, could I just have a chunk of polystyrene sandwiched in the middle (how do you grind up small amounts of polystyrene)?

    We use a small ball mill called a Wig-L-Bug.
