Certification testing using reference methods

Formaldehyde monitoring

Formaldehyde is too reactive to monitor by TD–GC–MS, and must instead be sampled onto DNPH cartridges, which generate a stable derivative. These cartridges are then analysed by high-performance liquid chromatography (HPLC). More on formaldehyde monitoring.

Reference methods used for final product certification require the evaluation of chemical releases from representative samples to be tested under simulated real-world conditions using small chambers, by accredited test laboratories.

Reference methods using this approach include:

Testing is carried out at a prescribed, near-ambient temperature and under a flow of pure, humidified air. VOCs and SVOCs emitted by the sample pass into the chamber/cell air and are collected at specific times – typically 3, 10 or 28 days – using sorbent tubes, which are then analysed by TD–GC–MS.
