TY - CONF A1 - Wilke, Olaf A1 - Pech, Anja A1 - Mull, Birte A1 - Horn, Wolfgang A1 - Jann, Oliver T1 - Determination of methanol and ethanol in test chamber air by using TDS-GC-FID N2 - A method for the determination of very volatile organic compounds (VVOC) in air was developed and successfully tested for methanol and ethanol. 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.

(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.

Foam tiles made from melamine resins are often used for acoustic insulation because they show good fire resistance and good thermal insulation properties. But they can emit formaldehyde. In Germany there are cases with a resulting indoor air concentration of higher than 100 µg/m³. In this study samples from two schools and one office were investigated. Additionally, new tiles were purchased and tested to evaluate the general potential as formaldehyde source.

The amounts of volatile organic compounds (VOC) which emit from products in emission test Chambers are used to evaluate these products. Typically labelling procedures for construction products are based on emission test chamber measurements. This performance should be verified. Possibly this can be performed due to testing of one material at different laboratories within a round robin test. Therefore it is necessary that a reference material exists which can be used for such round robin tests or as part of the quality management System to ensure comparable results. The different Statistical evaluation possibilities of a round robin test with a constant reference material for VOCs (volatile organic compounds) in emission test Chambers are the main focus of the presented paper.
