Two-dimensional gas chromatography (GC×GC) and GC×GC-time of flight (TOF)-mass spectrometry (MS) have received increasing attention as powerful techniques for separation and analysis of extremely complex mixtures. Over the past 20 years, solid-phase microextraction (SPME) has become a staple ...
But even when all these conditions are met, users can be held back by the more subtle elements in GC–MS operations, such as cutting or changing a column, or setting up the same experiment on different equipment. Even getting the parameters of a test organized so that it can ...
