FREQUENTLY ASKED QUESTIONS

What is sensory analysis of odors?

Sensory analysis of odors is a strategic method used in perfumery, cosmetics, flavors, and environmental applications to evaluate the overall olfactory profile of a product. It relies on trained expert panels to detect olfactory characteristics, off-notes, contaminations, and to assess fragrance performance.

What is gas chromatography-olfactometry (GC/O)?

GC/O is an advanced analytical technique that separates the volatile compounds of a sample and identifies those that influence its smell. It is essential for determining odor-active compounds, tracing the source of odor nuisances, and optimizing fragrant or aromatic formulations.

What is the analysis of volatile organic compounds (VOCs)?

VOCs analysis, including BTEX (benzene, toluene, ethylbenzene, xylenes) and residual solvents, is crucial for ensuring safety, regulatory compliance, and quality of perfumed, cosmetic, and industrial products.

Why is the Headspace (HS) technique important for VOC analysis?

Headspace sample preparation, including solid-phase microextraction (SPME), is essential for isolating relevant volatile fractions, improving reproducibility, and preserving the integrity of volatile profiles—particularly in complex matrices such as creams or natural extracts.

What are the risks associated with residual solvents in perfumed products?

Residual solvents can impair olfactory quality and product safety. They must be strictly monitored to comply with regulations and avoid any adverse impact on consumer health.
