01 Solution Summary
Medical polymer materials are pyrolyzed under a controlled temperature program, and volatile pyrolysis products are transferred online to GC or GC-MS to characterize the volatile and semi-volatile components generated by thermal pyrolysis of the material. Quantitation and quality control use the following arrangements: calibration relationships are established using reference materials matched to the detection channel for the volatile and semi-volatile components generated by thermal pyrolysis of the material; the qualitative basis, quantitative method, and result units are all subject to the applicable method; blanks, calibration checks, parallel samples, and quality control samples form batch quality control. The analytical batch is simultaneously set up with blanks, calibration checks, and applicable quality control samples.
