Sampling, Desorption, Analyses1.3 All emissions were calculated as area specific emission rate SER with the following formula:SERA = C x n / LWith:SERA C n LArea specific emission rate, µg/m2h Concentration in test chamber, µg/m³ Air exchange rate = 0.5 1/h Loading factor = 0.007 m²/m³1.3.1 Testing of VOC, SVOC, VVOC after 28 Days The emissions of organic compounds after 28 days were tested by drawing air samples from the chamber outlet through Tenax TA tubes (main tube and backup tube). Analyses were done by thermal desorption and gas chromatography / mass spectroscopy (internal methods: 9812 / 2808).Quantification was done with the Total Ion Chromatogram (TIC) signal, or in case of overlapping peaks by calculating with fragment ions. All identified and non-identified substances were quantified as toluene equiva- lent if giving more than 2.5 µg/m²xh.
