WebMar 9, 2011 · The hexanal measured by SIFT-MS resulted in a higher correlation coefficient (r = 0.936) than that obtained using SPME-GC-MS (r = 0.927). SIFT-MS is shown to be a fast, real time analytical technique for monitoring changes in the profile of volatile compounds in dry fermented sausages during processing and a useful tool to evaluate the oxidative … Webof a GC-MS. In most cases, parallel properties (retention time, isotope ratios) are required to consider the results confirmatory. GC-MS…How can that work? A major concern coupling a GC to a MS is the significant differences in pressure-the GC gas exiting the system is around one atmosphere (760 torr) whereas the MS operates at a vacuum of ...
