The QUADJET Thermal Modulator from LECO delivers industry-leading performance for comprehensive two-dimensional gas chromatography (GC×GC). Compared to alternative thermal or valve-based modulators, QUADJET stands out for its exceptional ruggedness, long-term reliability, and superior modulation efficiency.
This GC×GC modulation system uses a dual-stage thermal jet modulator positioned between the first- and second-dimension columns. The design enables true on-column cryo-focusing, significantly enhancing peak sharpness, detectability, and separation power—especially for co-eluting compounds in complex sample matrices.
Key benefits
- Highest modulation performance for GC×GC
Enhances peak detectability and improves separation of co-eluting compounds. - Dual-stage thermal jet design
Provides efficient trapping and re-injection between columns. - On-column cryo-focusing
Improves sensitivity and separation of closely eluting analytes. - Exceptional robustness and reliability
Designed for routine, long-term GC×GC operation.
Thermal modulation without liquid nitrogen
Unlike traditional cryogenic modulators, the QUADJET thermal modulator is consumable-free. It delivers the full performance benefits of thermal modulation without the need for liquid nitrogen, eliminating cryogen costs, logistical complexity, and downtime—while maintaining consistent, high-quality results.
The QUADJET Thermal Modulator is an ideal choice for laboratories seeking maximum GC×GC performance with minimal operational burden, particularly in demanding applications involving highly complex samples.
