| titleOfInvention | Measurement method for residual amount of pentachlorophenol in cigarette paper |
| abstract | A measurement method for the residual amount of pentachlorophenol in cigarette paper is characterized by comprising the following steps: cutting cigarette paper into pieces, adding extract liquor into the pieces, conducting ultrasonic extraction and measuring the residual amount of pentachlorophenol in the cigarette paper with liquid chromatography-tandem mass spectrometry (LC-MS/MS) directly after centrifugation of the extract liquor. The method comprises the following steps: a. cutting a cigarette paper sample according to relevant regulations; b. extracting a sample; c. purifying the sample; d. preparing a standard operating solution; e. carrying out liquid chromatography-tandem mass spectrometry (LC-MS/MS) measurement; f. calculating the measured result of the residual amount of pentachlorophenol. In comparison with the prior art, the measurement method has the following advantages: 1. adopting a pre-treatment of cutting the sample to make a solvent contact the sample better. The experiment result shows that such treatment can help to increase the extraction efficiency of pentachlorophenol. 2. measuring the content of pentachlorophenol in the paper with LC-MS/MS without derivatization operation, and the pre-treatment method is simple. 3. The method is accurate in operations, high in sensitivity and good in repeatability. |
