We developed a rapid grading method for recycled polypropylene using pinpoint thermal desorption and corona discharge ionization MS. The technique detects key additives with ~10 ppm sensitivity and enables material classification based on spectral profiles, supporting efficient quality assessment and application matching in plastic recycling.
