Mass Spectrometer Source Cleaning

A small buffing wheel is used

to polish metal filament and

source parts to a high luster.

Parts are thoroughly cleaned

in solvents and rinsed in a

state-of-the-art

ultrasonic aqueous

cleaning system.

Service Notes

Source cleaning begins with the complete disassembly of the

source. The metal parts are cleaned and polished, then washed in

solvents and baked out in an oven. All ceramic insulators are

sandblasted followed by solvent washing and bake out. If broken,

most of these ceramics can be replaced at no extra cost, with the ex-

ception of those with a cost of $50.00 or more. Vespel insulators are

washed in solvent and baked out. If old filaments are included on the

source they are repaired at no extra charge.

Additional charges may be incurred if metal parts, source heaters,

thermocouples or filaments damaged beyond repair need to be re-

placed. If Vespel insulators are broken or missing, they will need to

be replaced at an additional cost.

After all parts have been repaired, cleaned and baked out, the

source is reassembled. The filament is reinstalled and accurately

aligned over the source hole. The source is checked for resistance

leaks as well as visual alignment of all parts.

Not included in repairs are the replacement of the filaments,

collectors, heaters, screws or other missing parts.

Normal turn around is 72 hours unless components need to be

replaced that we need to custom order from the manufacturer.

24 Hour Turnaround on Source Cleaning

For rush 24 hour turn around, sources should be sent to SIS via

Federal Express or other overnight carrier. Once received, they will

be cleaned and shipped 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, please include a copy of the

manufacturers assembly instructions and schematic of the source

assembly.

Shipping in for Repair

Normally the source block and associated parts should be

shipped in for repair. The source should be thoroughly wrapped in

packaging material and double boxed to avoid damage in shipment.

If available, a copy of your source assembly/disassembly schematic

from your mass spec manual should be sent in with your source.
