This week Luz finished performing headspace analysis of volatile liquids, hexane and gasoline, on four sample fabrics. These fabrics are denim, linen, polyester, and nylon. The headspace analysis using the GC-MS instrument has shown– through chromatograms and mass spectra, that this method is most likely not sensitive enough to detect the molecules or that the method needs to be adjusted. This is where Luz will get to add in solid-phase microextraction (SPME) to work on improving sensitivity!
