Electron Multiplier
Electron Multiplier from Agilent
Agilent's high quality Electron Multiplier for ICP-MS is an important accessory in an effective, precision system. The electron multiplier converts incident ions into an amplified electric current used to record measurements of the ion signal. As the voltage in the system increases the amplification factor (or gain) increases. In general the Electron Multiplier can measure a count of 1.6E10. The system should be replaced when the total ion count reaches more than 3.2E11 and the sensitivity is less than 4000 counts with 10 ppb Y (even when applying detector voltage above 2700V).
- The Agilent Electron Multiplier converts incident ions into an amplified electric current in a stable, precision process
- The low noise currents created are used to measure the ion signal from sample in a wide variety of ICP-MS applications. Counts of 1.6E10 may be achieved.
- As voltage increases the amplification factor (also known as gain) increases in the system
- The electron multiplier should be replaced when the total ion count reaches more than 3.2E11 (this value is displayed in the software run time window) and the sensitivity is less than 4000 counts with 10 ppb Y (89 amu), even when applying detector voltage above 2700V
