3 Terms and definitions
The terms and definitions defined in GB/T 5327-2008 and the following apply to this document:
3:1
surfaceactiveagent
A surface-active compound that dissolves in liquids, especially water, due to preferential adsorption on the liquid/gas surface or other interfaces:
Surface tension or interfacial tension is significantly reduced:
Note: Surfactant refers to a molecule that contains at least one group with affinity for significantly polar surfaces (to ensure its water solubility in most cases):
) and a non-polar group with little affinity for water:

3:2
detergent detergent
The scrubbing process uses specially formulated products for cleaning:
Note: Detergents usually include main components (surfactants) and auxiliary components (builders, etc:):

4 Principles
After the sample is digested with acid, the sample solution is brought into the atomization system by the carrier gas for atomization, and then enters the plasma pass in the form of aerosol:
It is fully evaporated, dissociated, atomized and ionized in high temperature and inert gas, and converted into charged positive ions through the ion collection system:
