Determination method based on supercritical fluid chromatography and post-column addition reaction of ionic liquid |
| abstract |
The invention discloses a determination method based on supercritical fluid chromatography and post-column addition reaction of ionic liquid, comprising the following steps: (1) using n-heptanol, tetrahydrofuran and water to prepare a supramolecular solvent; (2) sample pretreatment: Use the supramolecular solvent to extract the sample to prepare the liquid to be tested; (3) use the method of supercritical fluid chromatographic separation, post-addition reaction of double-cation ionic liquid chromatographic column combined with electrospray mass spectrometry detection to detect the liquid to be tested. of perfluorinated compounds. The invention adopts the method of supercritical fluid chromatographic separation, post-addition reaction of double cationic ionic liquid chromatography column, and detection by electrospray mass spectrometry to establish a new analysis method for detecting perfluorinated compounds in textiles. Positively charged adducts are formed with the electronegative compounds to be analyzed during electrospray, and the analytes are detected by positive ion mass spectrometry mode to enhance signal sensitivity. |
