摘要

氯化氰是一种全身毒性物质，可迅速导致死亡。本文设计了一种非色散红外传感器，用于800 cm−1波段的氯化氰红外吸收检测。通过实验分析了内涂层材料的粗糙度，并选择了镀金气室。模拟了不同截面毒气室的光路传播，选择圆形截面毒气室增加红外探测器信号。研究了流量对电压的影响。在0.4 L min−1的最佳条件下，得到了电压与浓度的标准曲线。最大反应时间为19 s, RSD < 2%。干扰实验结果表明，进入气室的普通气体不会产生干扰。该非色散氯氰红外传感器具有稳定性好、实时检测氯氰的特点。

A non-dispersive infrared sensor for real-time detection of cyanogen chloride

Cyanogen chloride, as a systemic toxic agent, can cause death rapidly. In this paper, a non-dispersive infrared sensor was designed for the infrared absorption detection of cyanogen chloride at 800 cm−1. The roughness of the internal coating material was analyzed by experiments, and the gold-plated gas chamber was selected. The light path propagation of different cross-section gas chambers was simulated, and the circular section gas chamber was selected to increase the infrared detector signal. The effect of flow rate on voltage was studied. The standard curve between voltage and concentration was obtained under the optimal condition of 0.4 L min−1. The maximum response time was 19 s, and RSD was less than 2%. The interference experiment results showed that common gases entering the gas chamber do not cause interference. The non-dispersive infrared sensor for cyanogen chloride has good stability and detects cyanogen chloride in real-time.
