A new era of turnkey GC×GC analysis for ASTM Analytical Instrumentation
As global adoption of Sustainable Aviation Fuel (SAF) accelerates, laboratories face mounting pressure to deliver faster, more insightful, and more reproducible characterisation of increasingly complex fuel blends. Responding to this industry shift, PAC Powered by AC has introduced Sustain2D, a transformative family of turnkey GC×GC-FID analysers engineered for the demands of ASTM D8396. By combining fl ow-based modulation, quantitative FID detection, and PAC Powered by AC’s proven global GC platform, Sustain2D brings advanced multidimensional chromatography into reach for routine laboratories, all without adding operational complexity.
Today’s SAF production landscape spans a wide range of technologies from HEFA, FT, and ATJ, to emerging pathways, each producing fuels with unique molecular profi les. Understanding these subtle yet consequential differences requires analytical resolution far beyond what traditional GC methods can offer.
Sustain2D is built for precisely this challenge. Its dual-column confi guration and fl ow-based modulation deliver high-resolution separation of paraffi ns, naphthenes, and aromatics, revealing the structured, highly resolved elution patterns needed for confi dent group-type quantifi cation. This clarity is essential not only
for accurate compositional analysis but also for blending decisions, certifi cation workfl ows, and compliance across diverse SAF and Jet Fuel matrices.
One of the most persistent obstacles to GC×GC adoption has been the operational overhead of cryogenic systems, external hardware, and complex confi gurations that create barriers to implementation. Sustain2D was designed to eliminate that friction entirely.
Each system arrives fully assembled, confi gured, and performance-tested for ASTM D8396, allowing laboratories to begin running methods immediately without any need for a specialised setup, no additional hardware, and no cryogenics required. Its fl ow-based modulator reduces bench space, lowers maintenance needs, and simplifi es ongoing operation. In practice, this means labs can introduce the resolving power of GC×GC without disrupting existing workfl ows.
Despite its advanced multidimensional capability, Sustain2D preserves the usability and reliability of a conventional GC platform. Built on the world’s most trusted GC architecture and equipped with a Flame Ionisation Detector, it delivers fast, quantitative hydrocarbon analysis through workfl ows analysts already know. Its automated liquid
autosampler, split/splitless inlet, dual capillary columns, and integrated fl ow modulator function as a tightly coordinated analytical ecosystem, ensuring stability and repeatability in every run. This familiar yet elevated design positions GC×GC not as a specialist’s tool, but as a dependable part of daily lab operations.
That dependability is reinforced by real- world performance. Sustain2D has been validated using gravimetric blends of paraffi ns, naphthenes, and aromatics, demonstrating accurate analyte transfer, optimised modulation timing, and clean, high- resolution chromatographic patterns. These capabilities are essential for modern SAF quality assurance, where laboratories must confi dently detect trace-level components and fully characterise fuel chemistry with uncompromising precision.
Sustain2D represents a signifi cant step forward in multidimensional chromatography, bringing regulator-ready, high-resolution GC×GC analysis to a broader range of laboratories than ever before. Its combination of turnkey simplicity, analytical power, and PAC Powered by AC’s longstanding application expertise sets a new benchmark for SAF and Jet Fuel characterisation.
For labs facing the growing demands of
ASTM D8396, Sustain2D delivers a new era of confi dence and capability, raising analytical accuracy without increasing complexity.
