即集成传感器根据获得的大量的干扰因素的参数值、样本甲醛浓度检测值与样本甲醛浓度实际值进行参数拟合,得到不同干扰因素对应的补偿系数;干扰因素的参数值包括温度值、湿度值、干扰物浓度值,即集成传感器进行参数拟合获得相应的温度、湿度、干扰物质的补偿系数,有效改善目前传感器响应输出对于环境参数的敏感性,规避环境参数差异对于检测响应输出结果的影响。
S3:使用获得的补偿系数,对样本甲醛浓度检测值进行校准。
使用获得的温度、湿度、干扰物质的补偿系数对样本甲醛浓度检测值进行校准,即校准输出模组算法。
S4:样本甲醛浓度检测值进行校准后,使用标准甲醛分析方法对校准后的样本甲醛浓度检测值进行验证。
为了进一步证明甲醛电化学传感检测器检测的甲醛浓度检测值的准确性,即采集同样的甲醛样品,利用标准甲醛分析方法检测甲醛浓度,标准甲醛分析方法为符合GB/T 18204.26的公共场所空气中甲醛测定方法,包括分光光度法和气相色谱法,使得该甲醛电化学传感检测器的检测范围、准确度、灵敏度具有可靠性,能够有效显示环境中甲醛的真实浓度。
