The world of GC-MS applications is constantly expanding, growing into novel applications and improving classical uses. To celebrate the advancements of this powerful technology, LECO and The Analytical Scientist created an eBook that takes a look at some of the emerging uses of GC-MS. From measuring volcanic emissions to predict eruptions to developing the ultimate untargeted technique with GCxGC-MS, these articles explore a variety of topics.
