Abstract

The harmful materials as volatile organic compounds (VOCS) that is easy for gas to be changedfrom liquid on ambient temperature, those should be controlled by Korea Chemicals Management Association. The VOCs samples should be collected directly in place so that those could be analyzed. Generally but it couldn'tavoid to have the risk of analyst. Moreover, if there is the place limited to entrance, it is impossible to collectdirectly and measure. Owing to such problem, it tried to be solved by open path FT-IR spectrometer that couldbe studied on the combustion gases within long path and VOCs samples were tried to measure to large volumeby remote and real time. Firstly, it was to investigate optimized measured length between the system and benzenesample of VOCs. As result, The optimized measured length was confirmed with 15 meter length and thequalitative analysis could be measured on seven VOC samples. The calibration curve as quantitative analysisof benzene samples could be worked. On the basis of the result, the system as remote monitor could showto have potentiality
