SpletAnalytical methods capable of detecting PDMS are required in order to determine the causes of these problems. For this purpose, time-of-flight secondary ion mass spectrometry (TOF-SIMS) is one of the most powerful techniques, owing to its surface sensitivity and selectivity, and thus has been widely used. 1) http://muchong.com/t-15616777-2 SpletTOF-SIMS and MALDI-TOF are two complementary techniques, whereas TOF-SIMS offers higher spatial resolution and MALDI-TOF extracts larger volumes implying higher ion yields allowing the detection of large molecules such as proteins (Fletcher et al., Reference Fletcher, Lockyer and Vickerman 2011).Both techniques give information to identify and … himyf online
