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.
S
cientific Instrument ServicesTM now offers mass
spectrometer source cleaning. Since we first advertised this
service in our January 1994 newsletter, many of our cus-
tomers have taken advantage of this offer. This is NOT an exchange
program. The same source that we receive from you is cleaned,
repaired and returned back to you ready to install into your mass
spectrometer.
24 Hour Turnaround 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 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.
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
exception of those with a cost of 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
replaced. 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 24 hours unless components need to be
replaced which we need to custom order from the manufacturer.
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
