FTIR Analysis for Plastic Bottle Resin and Additive Identification

I’m requesting Fourier Transform Infrared Spectroscopy (FTIR) testing to analyze a plastic bottle sample. The objective is to identify the resin type and detect the presence of additives such as calcium carbonate (CaCO₃) in the material composition. I need confirmation on whether FTIR can accurately determine both the polymer base and filler content.
