A novel suite of instrumentation for the characterisation of materials held inside an air-tight tube furnace operated up to 250 °C has been developed. Real-time detection of released gases (volatile organic compounds (VOCs), CO₂, NO, NO₂, SO₂, CO and O₂) was achieved combining commercial off-the-shelf (COTS) gas sensors and sorbent tubes for further qualitative and semi-quantitative analysis by gas chromatography-mass spectrometry coupled to thermal desorption (TD-GC-MS). The test system was designed to provide a controlled flow (1000 cm³ min⁻¹) of hydrocarbon free air through the furnace. The furnace temperature ramp was set at a rate of 5 °C min⁻¹ with 10 min dwell points at 70 °C, 150 °C, 200 °C and 250 °C to allow time for stabilisation and further headspace sampling onto sorbent tubes. Experimental design of the instrumentation is described here and an example data set upon exposure to a gas sample is presented.

已开发出一套新颖的仪器，用于表征在最高250°C的气密管式炉内所盛物料的特性。结合商用现货（COTS）气体传感器和吸附剂管，可以实时检测释放的气体（挥发性有机化合物（VOC），CO ₂，NO，NO ₂，SO ₂，CO和O ₂）气相色谱-质谱联用热脱附（TD-GC-MS）进行定性和半定量分析。该测试系统被设计为提供通过炉子的受控的不含烃的空气流（1000 cm ³ min ^-1）。炉温梯度设定为5°C min ^-1在70°C，150°C，200°C和250°C的温度下具有10分钟的驻留点，以留出稳定时间并在吸附剂管上进一步进行顶空进样。这里介绍了仪器的实验设计，并介绍了暴露于气体样品后的示例数据集。
