  • In order to meet the needs of environmental monitoring, one gas absorption pool was developed. The gas pool could monitor the composition of volatile organic compounds (VOCs) on-line with high sensitivity and high fidelity, and was suitable for the equipment with Fourier transform infrared spectrum detection device. The method of combination of finite element analysis and optical trace was used to do optimization design of gas pool lens clamping adjustment and the fixed mode of optical whole structure. The problem of distortion correction of optical devices in VOCs monitoring of gas pool was solved effectively. The energy transmission efficiency can be optimized in the working range of 80℃ to 180℃. The method of optimization design of absorption pool output energy, suitable for VOCs gas and at specific temperature, was presented. Based on the method, one type of gas absorption pool was designed and the thermal environment test was carried out. The results show that, the absorption pool has stable transmission efficiency in the working range of 80℃~180℃ and can be applied in on-line VOCs sensing system.
