I sent my earlier post, “Switching from Helium to Nitrogen Carrier Gas for GC by Switching from a 30m x 0.25mm x 0.25µm Column to a 20m x 0.15mm x 0.15µm Column” to Roy Lautamo at Restek West for review, as he has a critical eye for particulars. He wanted to see finer detail in the elution area starting around 1400 sec in the first figure and took a sideways swipe at me by calling what I showed “chromahistograms”. Indeed! He also asked about peak widths, so I post some here for comparison, and I even included elution temperatures. The zoomed in chromatograms in that 1400+ sec region look very similar to me.
