GC×GC data is acquired by a detector in a linear (1D) format, so specialist software is required to ‘fold’ the data in order to view colour and surface plots.
ChromSpace allows GC×GC to be a productive contributor in any high-throughput laboratory, by enabling sophisticated peak merging, flexible data navigation and streamlined workflows.
Time-saving features, such as instant display of library matches and dynamically-linked panes, make GC×GC data exploration effortless, while a unique combination of peak perception algorithms ensures that even trace-level, masked peaks are not overlooked or incorrectly merged.
Product benefits:
- Customisable layout to suit all users.
- Global deconvolution to expose hidden peaks.
- Simplified, user-friendly quantitative workflow.
- Simultaneous acquisition and processing of MS (.lsc and .cdf) and single-channel data, e.g. FID.

Automated aroma profiling of wine using sorptive extraction with GC×GC-TOF MS/SCD
This study demonstrates the use of headspace sorptive extraction coupled with GC×GC–TOF MS/SCD to provide comprehensive information on wine aroma and odour taints on a single, fully automated, cryogen-free platform. The added value of Tandem Ionisation® for confident identification of aroma-active species that can be challenging to identify by conventional 70 eV electron ionisation alone is also shown.
GC×GC Applications Guide
GC×GC first attracted attention in the late 1970s, but for many years advances in conventional GC–MS meant that its superior separation capacity was not seen as being worth the additional technical complexity.
Thanks to greatly improved hardware and software, this has changed, and as a result GC×GC is now being routinely used in a variety of fields. This guide demonstrates just some of the most important applications.
