  • GCxGC is an ideal tool for complex samples
  • Increased peak capacity, improved peak resolution,
  • Up to an order-of magnitude increase in compound detectability.
  • Higher peak capacity, so more analytes separated
  • Structured chromatograms
  • Improved sensitivity


LECO’s comprehensive two-dimensional (GCxGC) system with FID, SCD, and/or ECD detectors is the appropriate choice for analytical procedures that demand more resolving power than standard GC can provide. LECO’s GCxGC solutions give unrivalled separating power, whether you need to speciate sulfur-containing chemicals in petroleum, separate halogenated insecticides, or quantify chiral compounds in tastes or perfumes.

The modulator’s concentrating effect creates sharp, narrow peaks with greater S/N than 1D GC (3–10 times more sensitivity).
Compounds belonging to the same chemical class can be found in the same region of the chromatogram, which is critical for group categorization and quantification.
