Des performances exceptionnelles pour la GC x GC de routine
Le modulateur de flux INSIGHT de SepSolve résout les problèmes de coût et de logistique liés au cryogène liquide nécessaire aux systèmes modulés thermiquement. De plus, il permet la séparation de composés volatils de C1 à C40+, sans risque de surcharge de la modulation, pour une meilleure caractérisation des pics de grande et de petite taille. Le modulateur INSIGHT intègre également un splitter pour une utilisation avec plusieurs détecteurs ainsi qu’une compatibilité avec la GC 2D heart-cutting.
Pour travailler en conjonction avec le modulateur de flux INSIGHT, SepSolve propose également le logiciel complet ChromSpace® pour GC×GC.

Reliable speciation of fatty acid methyl esters (FAMEs) by flow-modulated GC×GC–TOF MS/FID with Tandem Ionisation
This study demonstrates the use of flow-modulated GC×GC to analyse a FAME standard and FAMEs from a butter extract, with simultaneous detection by TOF MS and FID for improved speciation.
Flavour profiling of milk using high‑capacity sorptive extraction and TD–GC×GC–TOF MS/FID
This study demonstrates the high performance of PDMS sorptive extraction probes, coupled with thermal desorption pre‑concentration and INSIGHT™ flow-modulated GC×GC–TOF MS/FID analysis, for the separation and identification of flavour compounds in milk.
Comprehensive analysis of coffee bean extracts by GC×GC–TOF MS
This study shows that GC×GC with time-of-flight mass spectrometry provides a high-performance solution for screening complex coffee-bean extracts for key aroma compounds.
Comparison of aroma compounds in whisky by SPME–GC×GC–TOF MS/FID
This study demonstrates the high performance of a flow-modulated GC×GC–TOF MS system, coupled with sample preparation by solid-phase micro-extraction (SPME), for the separation and identification of trace volatiles in three brands of whisky.
Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation
In this study, we use thermal desorption (TD) for collection and analysis of whole cigarette emissions, and couple it with flow-modulated GC×GC–TOF MS, to enable smoke constituents to be routinely and confidently sampled, separated and identified.
Tackling the extended list of fragrance allergens by flow-modulated GC×GC–TOF MS/FID
This preliminary study investigates the use of flow-modulated GC×GC to analyse an 84-component allergen calibration standard, with simultaneous detection by TOF MS for confident identification and FID for robust quantitation.
Enhanced separation of hop oils by flow-modulated GC×GC–TOF MS
This study demonstrates the high performance of a flow-modulated GC×GC–MS system for the evaluation of complex hop oils, which allows effective modulation of even the most volatile components without the need for expensive liquid cryogen.
Detailed characterisation of essential oils by flow-modulated GC×GC and Tandem Ionisation mass spectrometry
In this study, flow-modulated GC×GC–TOF MS with Tandem Ionisation is used to characterise essential oils in fine detail, allowing the indepth comparison of their compositions that aids rigorous quality control, particularly in the fragrance industry.
