Polyethylene glycol 300 (PEG 300) and polypropylene glycol 425 (PPG 425) were analyzed using size exclusion chromatography (SEC) in different solvents, normal and reversed phase liquid chromatography (NPLC and RPLC), supercritical fluid chromatography (SFC), and matrix‐assisted laserdesorption/ionisation time‐of‐flight mass spectrometry (MALDI‐TOF‐MS). In liquid chromatography, different detectors were used: density, refractive index (RI) and evaporative light scattering detector (ELSD).
