| titleOfInvention | Method for detecting photoinitiator in printing packaging material |
| abstract | The invention relates to a method for detecting a photoinitiator in a printing packaging material. The detection method comprises the following steps: extracting the photoinitiator in the printing and packaging material by using a solvent, and filtering to obtain a solution to be detected; performing ultra-high performance phase-combination chromatography tandem connection on the solution to be detectedAnd (4) performing mass spectrometry, and quantitatively calculating the content of the photoinitiator. The method for detecting the photoinitiator in the printing packaging material provided by the invention extracts the photoinitiator in the printing packaging material and adopts ultra-high performance integrated chromatography tandem mass spectrometry (UPC) 2 MS/MS) analysis, has the characteristics of simple and convenient operation, short time consumption and environmental friendliness, can realize high-sensitivity detection of the residual photoinitiator in the printing packaging material, and improves the detection accuracy of the trace photoinitiator, thereby providing reliable data support for migration rule research of the photoinitiator. |
