What is the difference: GC,GC-MS vs. GCxGC-MS? #172

What is the difference between GC,GC-MS and GCxGC-MS spectroscopies? Or is it the same just abbreviation has a typo?

Note: fileio--fileformats.txt

bryanhanson commented 4 years ago

No typos. GC is "gas chromatography", MS is "mass spectrometry". GC-MS is a so-called hyphenated technique in which GC does the separation and MS does the detection. GCxGC-MS has two different GC columns for separation followed by MS detection... Does that help?
