Description
The PC3 is a small, robust Peltier cooled cyclonic spray chamber. The PC3 offers the advantages of low memory effects, constant temperature, fast rinse-out, and high sample transport efficiency. The cooled outer walls of the PC3 spray chamber enhance long-term signal stability, reduce polyatomic interferences such as oxides, and reduce solvent loading when volatile organic solvents are analyzed.
The Stable Sample Introduction (SSI) spray chamber is an all-quartz, O-ring-free spray chamber with an additional mixing chamber to homogenize sample aerosol prior to introduction to the ICP-MS. The SSI chamber improves short-term stability for isotope ratio measurements. The spray chamber may be combined with PC3 to enhance long-term stability. The SSI or PC3-SSI not only improves isotope ratio precision, but is useful for any analysis where better short- and/or long-term signal stability is desired.
Benefits of SSI
Improves signal stability roughly 2x to 3x
Improves isotope ratio precision up to 5x
Reduces cone deposition
Virtually eliminates the possibility of a flooded torch and the resulting instrument damage
Benefits of SSI with PC3
Constant temperature improves long-term stability
Reduces oxides and polyatomic interferences
No separate chiller required
Very low maintenance
