[Analysis Case] Quantification of water generated when heating water-absorbent polymers.
This article presents a case where water adhered to the surface of nylon 6, known as a water-absorbing polymer, and water generated during thermal decomposition were quantified separately.
The TG-MS (Thermogravimetric-Mass Spectrometry) method involves introducing gases generated during the TG-DTA (Thermogravimetric Differential Thermal Analysis) measurement of a sample online to a mass spectrometer (MS) for analysis. This technique allows for the acquisition of information regarding the thermal decomposition behavior of the sample, the types of gases generated, and the temperature ranges at which these gases are produced. Additionally, by creating a calibration curve using standard substances, it is possible to quantify the generated gases. [Analysis Sample] Nylon 6 (PA6) [Analysis Equipment] TG-DTA: Rigaku Thermo plus EVO2 GC-MS: Agilent 8890GC/5977B Inert Plus [Analysis Results] The TG-MS method allows for the quantification of water generated from the sample, separated by temperature. [Summary] Using the TG-MS method, it is possible to understand the amount of moisture adhering to the sample length and the amount of moisture generated during thermal decomposition.
