| Zusammenfassung: | The invention provides a Raman spectrum method for rapidly testing moisture content in triethylene glycol. The method comprises the following steps of: acquiring Raman spectrums of triethylene glycol within 120cm to 1000cm by utilizing a Raman spectrum technique, making a standard curve of the moisture content in triethylene glycol according to Raman spectrum intensity corresponding to a characteristic wave of triethylene glycol at 886cm to obtain a regression equation, and carrying out the test on the moisture content in triethylene glycol according to the regression equation. The method is rapid, simple and convenient to operate, small in sample consumption and applicable to on-site test. |
