Abstract
This paper presents a high-sensitivity organic contaminants detection method for clean room air. Using a Fourier Transform Infra-Red spectroscopy (FTIR), we can detect various chemical compounds including organic contaminants in a few minutes. In addition, by combining two efficient methods: Multiple Internal Reflection (MIR) and Cold Trap (CT), the sensitivity rate of detection chemical compounds rises drastically. By conducting experiments, it has been demonstrated that this sensitivity rate reaches to the order of ppb. This method will be used as an integral part of clean room air monitoring systems.
