Method summary: The sample is dissolved or swollen in a certain volume of tetrahydrofuran solvent, which contains a known amount of n-undecane as an internal standard. Use a micro-injector to absorb an appropriate amount of solution, directly inject it into a gas chromatograph or GC-MS instrument, perform gas chromatography or GC-MS analysis under certain conditions, and use the internal standard standard curve method for quantification.
