  • SISAlloy Filament Repair, repairs using the SISAlloy fillament material. SISAlloy contains pure rhenium doped with a small concentration of Yttria, in order to allow a longer fillament lifetime;
  • Yttria Coated SISAlloy Filaments, repairs using SISalloy filament wire can be coated with Yttria in order to improve filament performance.

In 1978 Scientific Instrument Services, Inc. began repairing mass spectrometer filaments and heaters. If you have any interests in the history of Fillament Repair, please take a look here. These days SIS has a team of dedicated engineers building and also repairing filaments.
