3 Terms and definitions

GB/T 6041, GB/T 13966, GB/T 14666, GB/T 23942, JJF1159, JJF1267 and the following terms and The definition applies to this document. 3.1 Inductively coupled plasma mass spectrometry After the element to be measured in the substance is ionized by inductively coupled plasma, the ions pass through the mass separator and are determined according to the mass-to-charge ratio (mass-to-charge ratio). A mass spectrometry analysis method based on the nature and quantification of the number of ions. 3.2 Central tube The aerosol formed by the atomizer is introduced into the channel in the center of the plasma, which is located in the innermost layer of the three-layer structure of the torch. Note. Also called injection tube or sample injection tube. 3.3 Auxiliary gas Argon flow between the middle tube and the center tube of the torch. Note. The role is to support the plasma formed at the torch mouth and control the plasma flame position, and protect the center tube.
