Finnigan MAT Filament / Heater Repair

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. 

FINNIGAN MAT 3000 SERIES, OWA, 5100, TSQ, INCOS 50.

Before repairing these filaments, they are completely disassembled, cleaned, and polished. All broken or cracked insulators and filament posts are replaced at no additional charge. Any copper wire lodged in the filament post support is removed and missing screws are replaced as required. In addition we have increased the filament tension to minimize sagging. All filaments are checked for final alignment on a Finnigan source to assure their optimum performance.

In addition S.I.S. has redesigned and manufactured these filaments to provide a filament with better performance. The following new filaments are available from SIS:

• 3000, OWA, Incos Metal Body Filament
• 3000 Source Block Heater
• 3200 Ceramic Body Filament
• 5100 Ceramic Body Filament
• 5100 Source Heater
• Incos Source Heater
• Incos 50 Ceramic Body Filament
• Incos 50B Ceramic Body Filament

FINNIGAN MAT 4000 FILAMENTS.

These filaments are completely disassembled, cleaned, and polished. All broken or cracked insulators (except the large sapphire plate insulator) are replaced at no additional charge. The additional cost to replace the sapphire plate insulator is $20.00 each. Any copper lead wire lodged in the support bracket is removed and missing screws are replaced as required at no additional charge.

All new filament posts are installed before the new filament ribbon is attached. A series of three jigs are used to install the filament wire, and final alignment is performed on a Finnigan 4000 source to assure accurate alignment and optimum performance. A New 4000 filaments, redesigned and manufactured by S.I.S., are also available from SIS. 

FINNIGAN MAT 4500/4600 and SSQ FILAMENTS.

In the repair of these filaments we have made a few changes to improve performance. The filaments are sandblasted with glass beads to remove all carbon residues. During the repair we have increased the filament tension to minimize sagging. In addition, we lowered the filament shield about 0.25 mm to help prevent the problem of the filament wire sagging and shorting out on the shield. Final alignment is performed on a jig for optimum performance of the filament.

The original Finnigan Mat 4500 filaments have a limited number of times that they can be repaired due to the soft ceramic used in their manufacture. Filaments not repaired will be returned unrepaired at no charge. S.I.S. manufactures a New improved 4500/4600 filament. This filament is stronger and will provide better performance than the original Finnigan filaments. 

FINNIGAN MAT ION TRAP AND MAGNUM FILAMENTS

Both the old style Ion Trap Filaments mounted on a flange and the newer plug in style Ion Trap Filaments are repairable. Even though each of these assemblies contains two filaments, the repair price for replacing both filament wires on the same assembly is the same as repairing single filaments for other instruments. For these repairs the assembly is sandblasted to remove all carbon residues and two new rhenium filament ribbons are spotwelded onto the support posts. The filament wires are aligned on a filament alignment jig to assure accurate positioning of the filaments and therefore optimum performance on your ion trap mass spectrometer.

SIS also manufactures New Ion Trap Filaments of the plug in style. 

OTHER FINNIGAN MAT/VARIAN-MAT FILAMENTS

We have repaired many different types and styles of filaments for the Varian-MAT/Finnigan-MAT instruments. Often we have seen three or more different styles and types of filaments used on the same instrument. As a result the repair of these filaments can be a little confusing. As a general policy, we will repair the filaments using the same type and size of wire that was originally attached when the filament was sent to us for repair. If you want it repaired differently, please advise us as to the type of wire or ribbon to be used in the repair. For example, we can repair many of the filaments using either a rhenium flat ribbon or a round wire for the filament material. Both types have been supplied by the manufacturer for the same instrument. Please specify which you prefer, otherwise we will install what was originally used on the filament press.

To repair these filaments we first sandblast the filament bodies with glass bead abrasives to thoroughly clean off all residues on the ceramic and metal parts. Often additional sandblasting of the ceramic parts with aluminum oxide abrasives is required to remove stubborn carbon residues baked into the ceramic matrix. The abrasive residues are thoroughly cleaned from the filaments and the filaments are baked-out to remove any further contamination. Most of the filaments are then repaired using a special high purity rhenium ribbon or wire. The MAT 250 filament uses a tungsten ribbon, and the MAT 112S or 8200 pin type filament is formed using a special rhenium/tungsten wire to make the pin type filament. Broken filament leads should be returned with the filaments, since they can be fused back in place at no additional charge. Broken filament posts can also be repaired at no additional charge.

In addition to filaments, we repair all MAT heaters. All heaters are repaired at the same price as filaments, with the exception of the MAT 44S heater. This heater has the heater coil embedded in ceramic which requires specialized machining during its repair. The MAT 44S heaters are repaired for $61.00. (P/N FILREP44S)
