Thermo (Finnigan) Mass Spectrometer Source Cleaning

A service from Scientific Instrument Services.

Scientific Instrument Services now offers a service of mass spectrometer source cleaning. Since we first advertised this service in our January, 1994 Newsletter, many of our customers have taken advantage of this new service. This is NOT an exchange program. The same source that we receive from you, it is cleaned, repaired and returned back to you ready to install into your mass spectrometer.

24 Hour Turn Around on Source Cleaning

For rush 24 hour turn around, sources should be sent to S.I.S. via Federal Express or other overnight carrier. Once received, they will be cleaned and returned the next day via an overnight carrier such as Federal Express. Please include your purchase order. If your source is not one of the ones listed below, please include a copy of the manufacturers assembly instructions and schematic of the source assembly.

Service Notes

Source cleaning includes our standard cleaning methods, outlined in our January, 1994 newsletter. All parts are thoroughly cleaned, rinsed in solvents and baked out in an oven and ready for installation into the mass spectrometer. Most ceramic insulators will be cleaned or replaced if broken (exception noted below). If old filaments are included on the source, they are repaired and are accurately aligned on the source using an optical video microscope system. If metal parts need to be replaced, this may delay return delivery until we can obtain replacement parts from the manufacturer and additional charges may be incurred. If the source heaters are sent in with your source, additional charges will be incurred if these items are damaged and need additional repairs or replacement. If available, a copy of your source assembly/disassembly schematic from your mass spec manual should be sent in with your source (only if your source is not listed below).

All the mass spectrometer sources listed below have been repaired by S.I.S. in the last few months. If your mass spectrometer source is not listed below, it can still be repaired by S.I.S. Just give Chris Baker or John Manura a call at: (908) 788-5550 to discuss the procedures involved in the cleaning of your source. Send your source with old filament(s) attached, along with a purchase order to: Scientific Instrument Services, Inc., 1027 Old York Rd., Ringoes, NJ 08551 Attn: Source Repair - Rush

Finnigan MAT Source Cleaning

Finnigan Source

Cleaning of the Finnigan MAT Sources begins with the complete disassembly of the source. Cleaning and polishing of all metal parts is followed by thorough washing and bake out in an oven. All ceramic insulators are sandblasted followed by solvent washing and bake out. Anodized aluminum insulators are washed in solvent and baked out. If these insulators are scratched or broken, they will need to be replaced at additional cost. The filament, collector and heater are cleaned and repaired if broken. These parts are not replaced if missing or damaged beyond repair. Replacement of these parts will incur additional costs. After all parts have been repaired, cleaned and baked out, the source is reassembled. The filament is accurately aligned over the ion entrance hole and clamped in place. The source is checked for resistance leaks as well as visual alignment of all parts. If the source is shipped with the source mounting flange assembly, the source is mounted onto this flange and all leads are connected and checked for continuity. If leads need to be replace, an additional charge will be incurred.

Parts Cleaned: entire source block, lens, insulators, collector, heater, filament and ion volume assembly.

Parts Repaired: Filament, collector and heater.

Parts replaced if missing or broken: Lens retainer springs

Not included in standard source cleaning price: replacement of castle spacer lens and lens ring retainer ceramic or anodized aluminum insulators. Also not included are the replacement of the filament, collector and heater assembly or any other missing mechanical parts.

Shipping in for Repair: Normally the source block and associated parts are shipped in for repair. The entire flange mounting assembly is not normally shipped for repair due to the heavy weight and delicate nature of this component. All source parts should be thoroughly packaged with packing material to avoid damage during shipment. If the Flange assembly is sent in for repair, it should be mounted on the original plastic mounting bracket supplied with the mass spec. This assembly should then be thoroughly packaged with packaging material and then double boxed to avoid damage in shipment. This flange assembly is very delicate and easily damaged in shipment.
