If samples are liquid solutions or can be easily dissolved in nitric, hydrofluoric, perchloric, or hydrochloric acid (or any combination thereof) the preferred method of sample introduction is by a nebuliser/spray chamber. The liquid is delivered via a peristaltic pump to the nebuliser, an example is shown to the right. The nebuliser creates a fine aerosol that is carried to the plasma by the argon nebuliser gas.
Here are some examples of solution ICP-MS we perform routinely:
