“…The extended results of this study showed that the degradation of polymeric materials and the rate of degradation within the human body depend on the biotic degradation, on the surrounding body environment and also the applied drug treatment. In addition to MALDI TOF MS, Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) are widely used for determination of low molecular weight compounds, as reported in several studies (Haider and Karlsson, 2002, Hillborg et al, 2001, Khabbaz et al, 2000, Flassbeck et al, 2001, Flassbeck et al, 2003, Gruemping and Hirner, 1999. The oxidative degradation of medical polymers occurs inside the human body and can be monitored in simulated environments (Backman et al, 2009, Kaali et al, 2010b.…”
