Maximum dissolved solid nebulizer

Maximum dissolved solids nebulizers [111] are usually cross-flow nebulizers operated at a high pressure. They are often made from PTFE, including the capillaries, and thus can be used for work with HF containing solutions. In this case a nebulization chamber made of PTFE and an ICP torch with an internal tube made of AI2O3 ceramics or BN should be used. 

An ICP-MS instrument will not tolerate dissolved solids at concentrations that can be run with an ICP-atomic emission spectrometer. In addition to increasing the probability of interelement (isobaric) interferences and signal suppression, high levels of dissolved solids condense on the sample-cone orifice. This deposition degrades the sensitivity and stability of the analytical signal. Typically, a maximum of 0.1% dissolved solids is recommended for continuous nebulization with a pneumatic...
