Objective To establish a method for the determination of aluminum in vermicelli by inductively coupled plasma mass spectrometry with quadruple collision reaction cell. Methods After microwave digestion, the sample was detected by inductively coupled plasma mass spectrometry. Matrix interference and signal drift were eliminated by the internal standard element 45Sc. Mass spectrum interference was eliminated by the collision reaction cell (KED mode). Results The correlation coefficient of aluminum correction curve was 0.999783. The limit of detection of the method was 0.045 mg/kg, the relative standard deviation was 0.79%, and the recovery rates ranged from 88.4% to 96.1%. The certified reference material of aluminum in starch noodles was in the range of certified value. Conclusion This method has high sensitivity, high accuracy and good precision, and is suitable for the determination of aluminum element content in powder strips.
