ost mass spectrometer filaments and heaters can

be repaired and restored to a like-new condition by

proper cleaning methods and by the replacement of

the filament ribbon or wire and heater coils. Scientific lnstrument

Services, Inc.™ repairs all of the filaments shown in the following

pages plus many others not shown or listed in the tables.

•

Filaments are thoroughly cleaned

•

Damaged or broken parts repaired or replaced

•

New filament aligned & spotwelded in place

•

This is not an exchange program. Your

filaments are repaired and returned to you.

Filament and Heater Repairs

We take pride in our workmanship and constantly strive to im-

prove the quality and performance of our repaired filaments. We

appreciate any feedback and suggestions from our customers.

Scientific Instrument Services, Inc.™ has been repairing filaments

for all models of mass spectrometers commercially for more than

35 years. In that time we have rebuilt tens of thousands of fila-

ments. We are constantly improving our techniques and adding

new equipment, tensioning and alignment jigs, and methodology

to our shops to provide the best possible filament repair. See our

web site for complete details.

EMERGENCY REPAIRS:

Emergency repairs can be

completed and shipped out within 24 hours of receipt of your parts

and purchase order. Parts can be shipped via FEDEX, if required.

Rush charges may be incurred.

SHIPPING INSTRUCTIONS:

Most glass parts and ceramic

insulators are very fragile and are easily damaged during ship-

ment. Therefore, please package all filaments carefully to avoid

damage during shipment. 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 FEDEX for

best shipping and handling.

Return Authorization Numbers Are Not

Required.

PRICES FOR FILAMENT REPAIRS

:

For the best prices, ship

filaments to us in larger lots. This reduces the cost of handling

and processing orders, thereby allowing us to pass the savings

on to you. Filaments and heaters from various manufacturers can

be combined to obtain the best prices.

OTHER FILAMENT REPAIRS:

In addition to the filaments

described herein, we can repair many other filaments. If your fil-

ament is not described in this catalog, give us a call. In these

cases, any information that you can provide such as a description

of the filament design or construction, composition and size of the

filament material, or drawings of the filament would be greatly ap-

preciated. If possible, send us a filament for repair with at least a

small piece of the original filament material intact. We will need

some of this filament material to determine its dimensions and

composition. Normal delivery on these special requests is 3 to 4

weeks when done for the first time.

Repair of Mass Spectrometer Filaments & Heaters

Four Types of Repairs Now Available at SIS™

As the world leader in developing new methods and new alloys

for mass spectrometer filaments, SIS can now provide four dif-

ferent types of repair for your mass spectrometer to provide for

improved performance.

Standard Filament Repairs - Part No. FILREP

Normally filaments sent for repair are repaired using the same

materials and filament geometry that was used in the original

manufacture of the mass spectrometer filaments. This is our

standard filament repair unless you request a different type of

repair such as the other configurations described below.

NEW - SISAlloy® Filament Repairs - Part No. FILREPA

SIS™ has spent more than four years developing this new alloy

of rhenium for mass spectrometer filament repair and manufac-

ture. Our research has shown that by alloying pure rhenium with

a small concentration of yttria, we have been able to improve fil-

ament performance by reducing warping and sagging of the fil-

aments. This alloy is now used in a variety of wire sizes and coil

sizes. See page A8

for additional details or visit our website for

the application notes on this new patented technology.

Yttria Coated Filaments Repairs - FILREPY

SIS™ can coat your standard repaired filament with yttria oxide.

Several manufacturers have used the yttria oxide coating on fil-

aments to increase filament emission and lower filament temper-

ates, which results in increased filament life. See page A9

for

additional details or the application note on our website.

Yttria Coated SISAlloy® Filament Repairs - FILREPYA

SIS™ has combined the two technologies above by yttria coating

our SISAlloy filaments. This provides a filament which will not

warp or sag and has greater emission and longer filament life.

See page A9

for additional details.

Save when you send 6 or more filaments at one time. Filaments

from various manufacturers can be combined to obtain the best

prices.

* - Thoria coated filaments must be handled carefully since thorium oxide is con-

sidered to be hazardous. Do not inhale or ingest the dust or fumes from these fila-

ments. Wash hands thoroughly after handling these filaments.

† - Price is per wire or coil (e.g. - If filament base holds two coils the cost is per coil or

wire.)
