采用动态顶空-热脱附-气相色谱/质谱（TD-GC/MS）联用技术，对喷涂聚氨酯泡沫塑料（SPF）进行了全自动微量气室分析。分析闭孔和开孔SPF样品的TVOC和高沸点化合物例如阻燃剂和胺催化剂的排放。对泡沫样品进行了定性分析，随后进行了15小时排放试验，以研究泡沫的排气机制。使用自动化序列检查样品温度的影响，其中样品温度在限定时间改变以模拟阁楼或屋顶中的泡沫隔热材料的加热。该实验提供了无人值守的操作，精确控制和记录的主要变量在微型室实验：时间，气体流量和温度。随后使用VDA 278方法在90°C下直接热解吸分析样品以确定VOC排放。从定性的角度来看，这两种方法之间有很好的相关性。半定量结果由聂云云1，艾凯Kleine-Benne 1，Kurt Thaxton 2 1获得。GERSTEL GmbH & Co.

An automated analysis system consisting of a dynamic headspace (DHS) system coupled with thermal desorption-Gas Chromatography/ Mass Spectrometry (TD-GC/MS) was used for fully automated microscale chamber material emission analysis of Spray Polyurethane Foam (SPF). Closed-cell and opencell SPF samples were analyzed for emissions of TVOCs and high boiling compounds such as, for example, fl ame retardants and amine catalyst. Foam samples were analyzed qualitatively, and 15 hour emission tests subsequently carried out to investigate off-gassing mechanisms of the foams. The effect of sample temperature was examined using an automated sequence in which the sample temperature was changed at defi ned times to simulate the heating of foam insulation in attics or roofs. The experiments provided unattended operation with precise control and documentation of the principal variables in micro-scale chamber experiments: Time, gas fl ow, and temperature. Samples were subsequently analyzed using the VDA 278 method with direct thermal desorption at 90°C to determine VOC emissions. Good correlation was obtained between the two methods from a qualitative point of view. Semi-quantitative results were obtained Yunyun Nie1, Eike Kleine-Benne1, Kurt Thaxton2 1. GERSTEL GmbH & Co.
