This overview provides guidance on implementing higher ion source temperatures for the 5975C series mass spectrometers and provides recommendations on how to choose an operating source temperature.
This technical overview discusses the implementation of high ion source temperatures for the Agilent 5975C Series Mass Selective Detectors (MSDs). While the default operating temperature is 230 °C, the 5975C ion source is fully configured for use up to 350 °C with the proper source configuration and ChemStation G1701EA software. The document outlines the advantages and disadvantages of higher temperatures, noting that while it can enhance signal for certain compounds like polynuclear aromatic hydrocarbons, it reduces source lifetime and requires strict leak prevention.
| Default ion source operating temperature | 230 °C |
|---|---|
| Maximum source temperature for 5973 and 5975A/B Series | 300 °C |
| Maximum source temperature for 5975C Series | 350 °C |
| Recommended baking temperature for quadrupole | 200 °C |
| Recommended baking temperature for source | 300 °C |
The 5975C MSD ion source is fully configured for use up to 350 °C.
Yes, an upgrade to the ChemStation software G1701EA (E.00.xx) is required.
Baking should be 6 hours or longer at the higher 350 °C temperature.
