Paint binders can be chemically analyzed using:

Question

Quizplus · Accepted Answer

TLC (thin layer chromatography) is not useful for analyzing paint binders as it cannot identify complex organic compounds.

IR spectrophotometry can be used to identify functional groups in the paint binder. However, it does not provide information on the specific compounds present.

Pyrolysis GC (gas chromatography) is a powerful technique for analyzing complex organic compounds. It involves heating a sample to high temperatures so that it breaks down into its component parts, which can then be separated and identified using GC. This method can provide detailed information about the composition of the paint binder.

Therefore, the best choice(s) for chemically analyzing paint binders are IR spectrophotometry and pyrolysis GC. The correct answer is D.
