Trifluoroacetic acid (TFA) has emerged as one of the most concerning PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
Amid this growing concern, liquid chromatography-mass spectrometry has never been more essential, and this is exactly where SCIEX and Phenomenex play a pivotal role.
TFA: A little‑known but ubiquitous “forever chemical”
A first-of-its-kind EU‑wide investigation by PAN Europe shows just how prevalent TFA contamination has become across cereal-based foods. According to the report:
TFA forms as a persistent degradation product from fluorine-containing gases (F-gases), pesticides and pharmaceuticals. Once released, it resists breakdown, accumulates in water, soil, crops, and, most critically, ends up in everyday foods.
The findings make one thing clear: food has become a major and underrecognized exposure pathway for ultrashort-chain PFAS such as TFA.
Why detecting TFA is so challenging
Unlike longer-chain PFAS compounds, ultrashort-chain species like TFA are:
This complexity is a major reason why TFA contamination has remained “unseen and unregulated” across Europe — until now.
To address this analytical gap, labs must rely on high-sensitivity, high-specificity mass spectrometry workflows capable of quantifying ultrashort-chain PFAS at low μg/kg or sub‑μg/kg levels.
SCIEX: Enabling accurate, defensible TFA testing in food
It has become increasingly important for labs to detect even the most elusive contaminants, including ultrashort-chain PFAS such as TFA.
Here’s how SCIEX and Phenomenex technology addresses the analytical challenges:
Modern triple-quadrupole mass spectrometers, including the SCIEX 7500+ system, widely used in PFAS research, provide the sensitivity and resilience required to detect ultrashort-chain PFAS, such as TFA, at trace concentrations.
For challenging PFAS assays, lab mangers need solutions that can deliver results time and time again. SCIEX and Phenomenex partner to combine expertise in PFAS testing and provide end-to-end solutions for robust and precise quantitation of PFAS compounds in a variety of matrices, enabling labs to:

Advanced analytical software platforms used in PFAS workflows help laboratories process and review large data sets and, separate true findings from matrix interferences, which are all critical when dealing with contaminants such as TFA. These platforms also support traceability and reporting, which become increasingly important as regulatory discussions evolve. SCIEX OS software provides a streamlined platform for acquisition, processing, QA/QC, and reporting across PFAS methods.
Why this matters now for food testing labs
Regulators are beginning to recognize the severity of ultrashort-chain PFAS contamination, but food-based monitoring is still limited. TFA currently escapes most EU food safety monitoring systems, leaving a major surveillance gap.
With rising consumer concern, growing media attention, and clear scientific evidence of widespread contamination, the demand for high‑quality, high‑sensitivity analytical data will only accelerate.

Finding the right information shouldn’t slow you down. Whether you’re troubleshooting your mass spec, learning something new, or optimizing performance, access to the right resources at the right moment makes all the difference.
As an analytical strategy, middle-down mass spectrometry (MS) workflows characterize biotherapeutic proteins by analyzing large, digested protein fragments or defined subunits, rather than fully intact proteins (top-down) or digested peptides (bottom-up). A middle-down strategy combines the strengths of top-down and bottom-up approaches by delivering high sequence coverage and structural specificity while maintaining relatively simple sample preparation. In practice, middle-down analysis enables accurate mass measurement, rapid sequence confirmation, and localization of key post-translational modifications (PTMs) on protein subunits that are directly relevant to product quality.
In biopharmaceutical development, sequence variants (SV) are considered an inherent risk of producing complex proteins in living systems. Sequence variants are unintended changes to the amino acid sequence of a biotherapeutic and can be caused by errors in transcription or translation in the host cell, or cell culture and process conditions. Detailed analysis of SVs is important in process and product development to ensure the drug’s safety and efficacy. Even low‑level sequence variants can have significant implications for product quality, safety, and efficacy, making their accurate detection and characterization a critical requirement across development, process optimization, and regulatory submission.
