(Salthammer, 2014) In Germany this will change because the latest version of the German AgBB scheme for health evaluation (2015) now include VVOC, e.g. ethyl acetate and ethanol. In this study selected compounds were tested with the procedure described in ISO 16017 and a method for measuring VVOC with thermal desorption was developed. Three different adsorbents Tenax TA, Carbograph 5TD and Carbopack X were tested to analyse VVOC according to ISO 16017. For the tested VVOC, Carbograph 5TD showed the best results under the chosen analytical conditions.

Carbotrap 300 (R) (a multi-bed tube using Carbopack C (R), Carbopack B (R) and Carbosive SIII (R)) was selected as sorption material for thermal desorption and tested for its suitability for emission test chamber measurements. The adsorption behaviour and the chromatographic results are influenced negatively by spiking aqueous solutions on the adsorption medium for calibration purposes. The latter effect can be reduced by blowing dry air across the adsorbent to remove the adsorbed water. Detection and quantification limits were determined for a GC-FID system and compared to GC-MS. The applicability of the method was tested with a methanol eliminating silane modified polymeric adhesive (SMP-adhesive for parquet) in an emission test chamber.

For these VVOC so-called LCI values (lowest concentration of interest) were derived which are used for the calculation of the so-called R-value (risk index, see reference 1 for the calculation). Test chamber measurements of particle boards show that the emissions of VVOC might have significant impact on the R-value and therefore for the health evaluation.
