| Abstract: | To develop an uncertainty evaluation method of vanillin in milk beverage by ultra Performance liquid chromatography mass spectrometry.The model and sources of uncertainty were founded through analyzing the whole determination procedure.The key uncertainty factors of affecting measurement results were synthesized and expanded.The measurement result is 0.312mg/kg±0.047,K=2.The results showed that the key factors of uncertainty attributed had five factors including sample amount,sample volume,sample concentration,repeatability,extraction recovery and the standard solution of sample concentration provided most contribution than others. |
| Keywords: | liquid chromatography-tandem mass spectrometry(LC-MS/MS) vanillin uncertainty milk beverage |
