Description:
Agilent/HP Filaments can be repaired by S.I.S. We will completely clean the assembly and replace the rhenium filament wire. This is not an exchange program. Your filaments are repaired and returned to you. For a complete description of this repair service see the section on Mass Spectrometer Filament Repair and Manufacture.
Return Authorization numbers are not required.
Standard Filament Repairs. All Agilent CI filaments can be repaired with the standard Rhenium wire that was used on all the original Agilent filaments. This is our standard filament repair. However they can also be repaired with SISAlloy® wire or Yttria coated SISAlloy for improved filament performance as described below.
SISAlloy Filament Repair. All Agilent 5975 4 coil filament can only be repaired by SIS using the new Rhenium alloy (SISAlloy®) developed by SIS. SISAlloy® 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 Coated SISAlloy Filaments. In addition the 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. See the review articles hyper-linked above for details on these processes.
Shipping Instructions:
Package filaments carefully when sending them in for repair
Most filament glass parts and ceramic insulators are very fragile and are easily damaged during shipment. Therefore, please package all filaments carefully to avoid damage during shipment. We recommend that you package the filaments personally. Filaments should be packaged in a box at least 6 inches square using packing peanuts or bubble pack as cushioning. We recommend shipping by UPS or Federal Express for best handling.
