レーザーラマン分光法による油様物質のその場識別手法の開発

摘要

We developed a laser Raman spectroscopy technique for the in-situ detection and identification of leaked oils around a transformer to determine whether the leakage originated from its container or an ancillary pipe. This technique successfully identified oil samples using the spectral differences observed in the 1000-3500 cm~(-1) spectral region. We also demonstrated the Raman identification of oils floating on the water surface as well as oils that were extracted from soils using water. Our results show that laser Raman spectroscopy is a useful method for the in-situ determination of oil leaking from transformers.
