We developed an AI-based EI mass spectral database with 120 million predicted spectra to improve unknown compound identification in GC×GC-MS beyond commercial library limits.

We’re pleased to release the first update for KnowItAll 2025, improving performance and fixing issues introduced since the major release featuring new tools and enhancements.

LC-GC×GC-FID/TOFMS enhances MOSH/MOAH analysis in food ingredients and additives, helping to resolve coelutions and reduce interpretation errors beyond current ISO 20122:2024 limitations.

Using the FDA's Century Mix, we developed a robust QA/QC system for untargeted GC×GC-TOFMS metabolomics, tracking 100 compounds to improve standardization, reproducibility, and long-term performance.

Can the design of a gas chromatograph (GC) impact the productivity of your laboratory? The answer is yes, especially when it allows you to work more efficiently.

Dry nitrogen is ideal for blowdown evaporation in labs—it's safe, inert, fast, prevents oxidation, and is cost-effective, especially with a nitrogen generator.

Ultrafine particles (UFP) <100 nm pose health risks due to deep lung penetration. This study uses DTD-GC×GC-TOFMS to reveal PAH profiles in ambient air UFP sampled in Augsburg, Germany, in 2023.

In the GC Orbitrap Guru Series, I talk with scientists, analysts, and experts to share their stories and experiences with GC Orbitrap mass spectrometry.

As a child, Tomáš Čermák struggled socially, but now, at 18, he's graduating high school, winning awards, and working with the Czech Academy of Sciences.

Using GC×GC-TOFMS, we assess cannabis exposure in mothers and infants via urine, milk, and passive samplers, identifying metabolites and informing prenatal care.
