Mass Spectrometer Filament Repairs

8 March 2021

We used to repair many mass spectrometer filaments, especially when their price is high. Most filaments could be repaired and restored. Our partner recently reviewed the list of filaments that can be repaired. We will be continuing to offer the repair service for the following filaments : Agilent 5971, 5972, 73, 74XX, 75 and 77 (EI & CI) ; Thermo DSQ and Ion Trap ; Shimadzu QP5000, QP2010/2020 and the PKI Marathon, CLARUS rhenium and tungsten filaments as well as the WATERS QUATTRO, AUTOSPEC and GCT ones.

We can also repair the EI JEOL ACCUTOF filament via another partner. We may continue to offer the repair of other OEM models but please contact us to check.

Lead times are at least 8 weeks for any repair.

Four types of repair are available, depending on the model of the filament:

Standard : repair with the wire that was used on the original filament.

SISAlloy® : repair with the rhenium alloy developped by SIS (pure rhenium doped with a concentration of yttria) to improve the strength of the rhenium and therefore filament performance.

Yttria coating : SIS uses the yttria oxide coating to increase filament emission and lower filament temperates. This results in an increase of filament life.

Yttria coated SISAlloy® : SIS combines the two above technologies to have a greater emission and a longer filament life.
