Repair of Mass Spectrometer Filaments & Heaters
Most mass spectrometer filaments and heaters can be repaired and restored to a like-new condition by proper cleaning methods and by the replacement of the filament ribbon or wire, and heater coils. Scientific Instrument Services, Inc. repairs all of the filaments shown in the following pages plus many others not shown or listed in the tables.
- Standard Filament Repairs. Filaments are repaired with the standard wire that was used on the original filament.
- SISAlloy® Filament Repairs. Filaments are repaired with Rhenium alloy (SISAlloy®) developed by SIS. SISAlloy which is an alloy of pure rhenium doped with a small concentration of Yttria. The Yttria improves the strength of the Rhenium. The electrical characteristics of SISAlloy are identical to pure rhenium, however the filament has less tendency to sag, thereby improving filament performance.
- Yttria Filament Repairs. Filaments are repaired with a Yttria coating applied to the original wire for improved filament performance.
- Yttria Coated SISAlloy® Filaments. SISAlloy® filament wire can be coated with Yttria for improved filament performance. Filaments coated with Yttria emit electrons at a lower filament current and therefore they run cooler. This results in longer filament life by 2 to 3 times.
