GC3: Comprehensive Three‐Dimensional Gas Chromatography |
|
| Authors: | Edward B. Ledford Chris A. Billesbach Quanyu Zhu |
| Abstract: | Comprehensive three‐dimensional gas chromatography (GC3) is demonstrated using modified GC×GC apparatus. A new thermal modulation scheme employing a single moving heater to operate two thermal modulators is introduced. Considerations of the bandwidth/resolution tradeoff of GC3 show that high‐speed tertiary columns would make GC3 practical, with modest loss of underlying GC×GC peak capacity. |
