Application of a new gas mixing device to test adsorptive wall materials (2009)
Richter, Matthias ; Horn, Wolfgang ; Jann, Oliver ; Brödner, Doris ; Till, Carola
With a gas mixing system (GMS) developed in our laboratory we created a gas mixture of four substances. Adsorptive wall materials of four different compositions were exposed to this gas mixture, consisting of 1-pentanol, hexanal, butyl acetate and n-decane. Aim of this study was to scrutinize the ability of these samples to reduce the concentration of the supplied gas. This capacity is expressed in the sorption flux F or area specific adsorption rate respectively. The test was performed referring to a draft of ISO 16000-24.

Correlation of aldehyde emissions and fatty acids content in pine wood and oriented strand boards (2011)
Wiegner, Katharina ; Brödner, Doris ; Horn, Wolfgang
Indoor air quality is important for human health and comfort. To ensure good indoor air quality contamination by volatile organic compounds (VOC) should be minimised. The aim of the project is the reduction of unsaturated aldehydes which can emit from oriented Strand boards (OSB): These aldehydes have an impact on the health based evaluation of emissions from products for indoor use according to the AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten, Committee for Health Evaluation of Building Products) scheine (AgBB 2010). The model OSB were produced in a pilot plant using well known raw materials (Pinus sylvestris at different trunk heights) under using various processing parameters (Wilke et al. 2011). OSB emit predominantly monoterpenes and aldehydes. Aldehydes are oxidation products of fatty acids in wood. The conditions which affect the oxidation process are the fatty acid concentration and composition, the oxygen content, the sample surface and the presence of compounds which indicate, inhibit or stop the oxidation respectively. The oxidation rate rises with an increasing number of double bounds in the fatty acid, e.g. the oxidation rate between oleic, linoleic and linolenic acid correspond to 1:12:24. One of the most important products of fatty acid oxidation is hexanal. It is generated during the oxidation of linoleic acid. This study shows a direct correlation between aldehyde emission and oxidation, hexanal can be used as an indicator for oxidation.

Mull, Birte ; Sauerwald, T. ; Richter, Matthias ; Horn, Wolfgang ; Brödner, Doris ; Schultealbert, C.
The aim of this study is the development of a reproducibly emitting reference material for volatile organic compounds (VOC). The first part of the work was carried out with styrene, for which supporting materials were successfully selected, doped and analyzed in test chambers.

Kurzfassung An neun verschiedenen Hardcopygeräten wurden in unterschiedlichen Emissionsmesskammern (zwei verschiedene 1 m³ - Kammern und eine 20 m³ - Kammer) in Kombination mit geeigneten Probenahme- und Analysenverfahren Untersuchungen zum Emissionsverhalten dieser Geräte hinsichtlich Staub, Ozon und VOC (TVOC) durchgeführt. Luftprobenahme und Analytik erfolgten für VOC mittels Tenax TA und anschließender Thermodesorption (TDS) in Verbindung mit GC / MS. Ozon wurde kontinuierlich bestimmt. Der Ozonanalysator arbeitete auf der Grundlage der flammenlosen Reaktion von Ozon mit Ethylen nach dem Prinzip der Chemilumineszenz. Die Staubbestimmung erfolgte gravimetrisch mittels Glasfaserfilter und Ultramikrowaage. Zusätzlich wurde die Partikelemission während des Druckbetriebes mit einem Partikelzähler bestimmt. Aufgrund der technischen Rahmenbedingungen standen nur kurze Druckzeiten von maximal 36 Minuten zur Verfügung. Um die Gleichgewichtskonzentration in der Prüfkammer zu erreichen, wurde die Luftaustauschrate in den 1 m³ - Kammern auf n = 4,0 bis 4,7 pro Stunde erhöht. Zusätzlich zur Prüfung in den Emissionsmesskammern sind verschiedene Papiere mittels Direkt - TDS sowie unter- schiedliche Toner mittels Headspaceprobenahme in Kombination mit GC / MS hinsichtlich ihres Emissionsverhaltens untersucht worden. Für die untersuchten Geräte wurden Emissionsraten ermittelt. Sie betrugen für TVOC 0,41 bis 22,4 mg pro Stück und Stunde, für Ozon kleiner 0,02 bis 4,6 mg pro Stück und Stunde sowie für Staub 0,10 bis 7,63 mg pro Stück und Stunde. Verglichen mit Frischfaserpapier wurden bei den Untersuchungen mit Recyclingpapier deutlich höhere SVOC - Konzentrationen nachgewiesen. Im Ergebnis der Untersuchungen wurde ein Prüfverfahren entwickelt, das die Basis für Emissionsmessungen im Rahmen der Umweltzeichen RAL –UZ 62, RAL –UZ 85 sowie des neuen RAL –UZ 114 für Multifunktionsgeräte darstellt. Abstract The emission behaviour with regard to dust, ozone and VOC (TVOC) of nine different hardcopy devices in combination with suitable air sampling and analysis procedures was investigated in different emission test chambers (two different 1 m³ - chambers and one 20 m³ - chamber). Air sampling and analysis for VOC were done by means of Tenax TA and subsequent thermal desorption (TDS) in connection with GC / MS. Ozone was determined continuously. The ozone analyser worked on the basis of the flame rid reaction of ozone with ethylene according to the principle of chemiluminescence. The dust determination was done gravimetrically by means of glass fibre filter and an ultra micro - balance. Additional the particle emission during the printing process was measured with a particle counter. The general technical conditions of the tested hardcopy devices were the reason for short printing times with a maximum of 36 minutes. In order to achieve the equilibrium concentration in the test chambers the air exchange rate in the 1 m³ - test chambers had to be increased to a value of n = 4,0 to 4,7 per hour. Additional to the examination of the hardcopy devices in the emission test chambers different papers were investi- gated by means of direct - TDS and different toners were tested by means of head space sampling in combination with GC / MS. For the examined hardcopy devices emission rates were determined. The emission rates for TVOC ranged from 0,41 to 22,4 mg per piece and hour, for ozone from less than 0,02 to 4,6 mg per piece and hour and for dust from 0,10 to 7,63 mg per piece and hour. The comparison between recycling paper and paper produced from primary fibres showed in general higher SVOC emissions from recycling paper. As the result of the investigations a test method for the determination of emissions from hardcopy devices was developed. This test method is the basis for emission tests in the framework of the German Award of the Environmental Label for office devices RAL -UZ 62, RAL -UZ 85 and the new RAL -UZ 114 for multifunctional devices.

Effects of emissions of materials for wrapping, transportation and storage on stained glass windows and on glass objects in show cases in museums (2008)
Torge, Manfred ; Wilke, Olaf ; Brödner, Doris
The emission of volatile organic compounds (VOC) of materials for wrapping, transportation and storage of stained glass windows were investigated by direct thermal desorption. The analysis was performed with thermal desorption in combination with gas chromatography and mass spectrometry. Emissions of organic acids were determined. The damage risk of volatile organic compounds, e.g. organic acids as acetic acid, propanoic acid, hexanoic acid and octanoic acid was investigated on model glasses in climate chambers. After exposure the surface of the most sensitive samples was damaged. Based on emission measurements in exhibit cases of the former museum "Grünes Gewölbe in the Albertinum" in Dresden, Germany, the atmospheric conditions inside the show cases were determined. It can be shown that the atmospheric conditions inside the cases endanger the glass and enamel objects of art especially in show cases with low air exchange rates. Materials with high emission rates of organic acids should not be in direct contact with medieval glass for a long time and should not be used in exhibit cases. Acid emissions, especially acetic acid plays an important role during investigation of different materials for show cases and can be determined by direct thermal desorption.
