ANALYZER CONSTITUTED BY GAS CHROMATOGRAPH COMBINED WITH INDUCTIVELY COUPLED PLASMA MASS SPECTROMETER |
摘要 |
The invention provides a new GC/ICP-MS capable of preventing carbon deposition caused by the analysis sample or its solvent. With a GC/ICP-MS, it is effective to introduce oxygen continuously or during a specific period to the part where argon or other makeup gas is introduced to the ICP-MS, and this is achieved by introducing oxygen in air into the gas supply line using an oxygen permeable tube or oxygen permeable membrane. A selector valve is used to introduce permeated oxygen to the aforementioned gas supply line only during a desired period. |
