Equipped with up-to-date control technology, this chamber allows climatic variables such as temperature, air humidity and air exchange to be set very precisely within a wide dynamic range and controlled automatically. Stainless steel surfaces on the inside have been treated so as to minimize possible sink effects. Interactions between the materials used in the emission chamber and the test body itself could otherwise cause inaccuracies and falsifications in the measurement results. Special attention was also devoted to the design of suitable sampling points. This new chamber makes available a technical solution on the real-room scale which has no qualitative counterpart anywhere in Europe.
The institute has also invested in the very latest analytical technology. In addition to the usual gas chromatography and mass spectrometry facilities, a proton resonance mass spectrometer now measures on a time-resolved basis the concentration of organic substances in the very lowest trace range. At their disposal the scientists also have various items of equipment for time-resolved determination of the numbers and the size distribution of fine and micro-particles.
