比色传感阵列在气味表征中的应用

Application of Colorimetric Sensor Array in Odor Characterization

汽车内饰材料种类繁多、成分复杂,单车型气味物质多达上百种,极易造成车内异味污染,为提高车内空气质量,参考国内外现有的比色技术应用研究,提出了基于比色传感阵列技术的车内气味检测方法,并对整车中应用较多的内饰材料进行比色分析,准确识别了内饰材料样品的气味强度、气味类型和气味愉悦度。首次将比色传感阵列应用于车内气味客观表征中,可为汽车气味管控提供数据支持。

Due to the variety of automotive interior materials,complex composition,and up to hundreds of kinds of odor substances inside each car,odor pollution easily occurs inside the car.In order to improve interior air quality,this study referred to the existing domestic and foreign research on the application of colorimetric technology,proposed an interior odor detection method based on colorimetric sensor array technology,and made colorimetric analysis on the interior materials widely used in the vehicle,accurately identified the odor intensity,odor type and odor pleasure of interior materials samples.In this study,colorimetric sensor array was applied for the first time in the objective characterization of vehicle odor,which can provide data support for odor control in the automobile industry.
