论文摘要
Terahertz attenuated total reflection（THz-ATR） spectroscopy has an expected poten-tial on detection of powder, thin film and especially for liquid samples in many tech-nical areas. One of the most important factors affecting reliability of data during THz-ATR spectra collection, especially for quantitative detection of trace amount of analytes, is the cleanliness of the ATR accessory after each measurement. In this study, we proposed an effective cleaning procedure to minimize the error from the residuals after each cleaning. The cleansing conditions of the ATR accessory（cleaning agent, flow velocity, and cleaning time） on THz-ATR detection were investigated through differentiation index, K-means clustering, and Euclidean distance. The results show that ethanol was the best cleaning agent followed by methanol and water. cleaning time and flow velocity both can improve the cleaning efficiency in the given ranges.
