  • What is GC x GC, How Does it Work and Why Do We Need It?

    GC x GC (or GC x GC x MS) separates about 20X more chemical compounds than conventional 1D GC with no run-time penalty, improves sensitivity by about 5X, and generates chromatograms far easier to interpret than those generated by 1D GC or 1D GCMS. In spite of its striking performance, GC x GC has been slow to catch on. Why? The adoption of any new analytical technology is inherently slow due to a variety of factors. This entertaining talk will demonstrate that GC x GC is easy to understand, revolutionizes the practice of gas chromatography, solves a host of problems that simply cannot be solved any other way, and reveals that our world is vastly more complex, chemically speaking, than we have realized heretofore.

      How wonder mine too 😊 it's left ear 😊 perhaps in this way what we have listened from left ear that would be remain inside ..Not to move out from right ear 😊

      Yeah ... and that could have been fixed in post production with a couple of mouse clicks (before uploading to YT) ... (but no one consulted an audio engineer)

      Maybe because you're only listening to the right channel and the video only has audio in the left channel
