For testing the comparability of TVOC measurement techniques, a 1 m³ stainless steel chamber, operated under dynamic conditions, was spiked consecutively with three VOC-mixtures. MI: aromatic hydrocarbons/ketones/esters(recipe of nitrocellulose lacquer): MII: components of the Molhave-mixture. MIII: terpenes/aliphatic hydrocarbons (recipe of eco-lacquer). Samples were taken on TENAX TA and analyzed according to the procedure recommended by EU-ECA. The measurements were performed by two laboratories using similar equipment and identical analytical procedures. In addition, the TVOC-values were compared with data obtained by a flame-ionization detector (FID) and a photoacoustic detector (PAD).
