3-in-1

Building materials and consumer products such as curtains, carpets, wall coverings, and mattresses are significant sources of volatile emissions (VOC, SVOC, and VVOC) that negatively affect indoor air quality. Until recently, it was sufficient to measure VOCs and SVOCs, but due to changing regulations and stricter requirements from health labels like OEKO-TEX®, it is now also mandatory to detect VVOCs. Current analysis methods and equipment are inadequate: they are slow, expensive, and unsuitable for measuring very volatile substances or moisture-containing natural materials such as cotton and wool.

As a result, companies struggle to meet all emission standards and label requirements, which threatens their market access and competitiveness. The lack of an integrated analysis method also hinders the development of healthier, innovative products.

The “3-in-1” project allowed us to introduce a new analytical device and testing method that enable simultaneous detection of VOC, SVOC, and VVOC in a single analysis. This is achieved using a Tenax-based multisorbent system, with each sorbent tailored to the volatility of the target compound.

1. Measurement of VOC, SVOC, and VVOC in one analysis using a Tenax-based multisorbent tube.
2. Direct analysis of air samples from various environments (e.g. production halls, shops) via modified metal canisters.
3. Direct testing of recycled textiles placed inside the canisters.
4. Analysis of natural, moisture-containing fibers (e.g. wool, cotton) without instrument freezing.
5. Separation of oil emissions into less harmful saturated compounds, toxic aromatic fractions (e.g. benzene derivatives), and odorous sulfur/nitrogen compounds using a GCxGC module.
6. Detection of very volatile PFAS compounds, currently not measurable.
7. Identification of heavier (semi-volatile) plasticizers typically found in flexible plastics or coated textiles.

This technique is safer for lab personnel and more environmentally friendly than solvent extraction. It enables faster, more cost-effective testing, supports product innovation, and contributes to healthier indoor environments.
