- Principles of method if other than guideline:
- This method is not performed to GLP standards; it is an in-house method developed for internal QC procedures under an ISO 9001:2015 accredited Quality Management System.
Perform DSC analysis according to the method below:
DSC method
Melting point determination of IPN by DSC
DSC is performed on a TA Instruments Q2000 DSC.
a) Weigh the sample (ca. 2 mg) into an aluminum Tzero Pan and seal it hermetically using with a Tzero Hermetic Lid.
b) Place the sample pan in a vacant position in the autosampler.
c) Weigh one empty aluminum Tzero Pan and seal it hermetically using a Tzero Hermetic Lid (Reference).
d) Place the Reference pan in a vacant reference position in the autosampler
e) Enter mass of empty sample and reference pans and the mass of the sample where appropriate in the DSC software.
f) DSC data file name must contain the full sample ID, i.e. IPN-xxx-20xx-001-1
g) Prepare custom method with following test parameters
i) Method (Load file QC-mDOB from the QDSC methods folder):
(1) Equilibration at 140°C
(2) Temperature is ramped at a rate of 1 °C/min to 180°C.
h) Determine the melting point using the Integrate Peak/Sig Horizontal function under “Analyze” header in the TA Universal Analysis software.
i) Print the thermogram as pdf and upload in line in conjunction with QC Data Storage Protocols - GLP compliance:
- no
- Remarks:
- study conducted to in-house methods.
