Nebulizer
The sample aerosol is generated by the nebulizer. The properties of the
aerosol can be influenced by the nebulizer gas flow and also by the type
of nebulizer employed. Depending on the model ordered, the nebulizer
is made of either polypropylene (PP) or perfluoroalkoxy (PFA), see
.
Spray Chamber
The spray chamber filters out larger aerosol droplets for improved signal
stability and low oxide rates. Depending on the model ordered, the
spray chamber is made of either quartz or PFA, see
.
