Automated system for online detection of organic molecular impurities in semiconductor-grade chemicals |
| abstract |
Embodiments of the analysis system may include an initial multi-port valve, at least one intermediate multi-port valve, additional multi-port valves, and a time-of-flight mass spectrometer (TOF-MS). The initial multiport valve can be configured to receive a sample. At least one intermediate multiport valve may be fluidly connected to the initial multiport valve and configured to receive a sample from the initial multiport valve. A given intermediate multiport valve may have an ion exchange column associated with it. A given intermediate multiport valve can be selectively configured to either direct the sample through its associated ion exchange column (in speciation mode) or bypass the ion exchange column (in injection mode). Additional multiport valves may be fluidly connected to and configured to receive a sample therefrom with at least one intermediate multiport valve. A time-of-flight mass spectrometer (TOF-MS) can be fluidly connected to the additional multi-port valve. |
