Comprehensive Two-Dimensional Gas Chromatography

The latest newcomer to the collection of GC techniques, GCXGC, is examined in this instalment. Although this technique is capable of delivering more GC information in a shorter time than other methods, its technical complexity has slowed down widespread acceptance. John Hinshaw explains...

Figure 2. Split injection used to measure triplicate test of MTBE, hexane, o-xylene, and 1-methylnaphthalene comparing different solvents (methanol, methylene chloride) and column insertion distances starting with 0.5 mm, 5.0 mm, 10.0 mm, 15 mm, and 20.0 mm. Methanol had the best performance at the 5.0 mm insertion distance and methylene chloride looked slightly better at the 0.5 mm. We would still recommend not going below the 5.0 mm manufacturer recommended insertion distance.
Revisiting Column Insertion Distance
Revisiting insertion distance for methanol and methylene chloride in GC analysis and confirming that insertion depth strongly affects response and reproducibility.
