| Abstract: | High field asymmetric ion mobility spectrometry(FAIMS) was applied to analyzing the migration of methyl methacrylate in water based food simulants without pretreatment processes, such as extraction or enrichment. By studying the influence of scanning times, sample temperature, sample volume, carrier gas flow-rate and solvent doping on the characteristic signal of methyl methacrylate, the detection limit of methyl methacrylate was determined to be 10 μg/L, and the relationship between the ion current intensity and the concentration of methyl methacrylate was established. The method proposed has the advantages of high sensitivity, easy operation and fast analysis, and can meet the requirements of practical work. |
