ETP Electron Multipliers
for Mass Spectrometry
• Proprietary specialized
surface material resulting
in very high secondary
electron emission.
• Air stable.
• 2-year shelf life guarantee.
• Discrete dynode design
results in extended operat-
ing life.
The electron multipliers manufactured by ETP use a proprie-
tary dynode material. This material has a number of properties
that make it very suitable for use in an electron multiplier. It
has very high secondary electron emission, which allows excep-
tional gain to be achieved from each dynode. This material is
also very stable in air. In fact, an ETP multiplier can be stored
for years before being used. As a direct result of the high stabil-
ity of the active materials used in ETP multipliers, they come
with a 2-year shelf life warranty (stored in original sealed pack-
age). Many testing laboratories take advantage of this long shelf
life by keeping a replacement ETP multiplier on hand, ready for
immediate installation. This keeps instrument downtime to a
minimum.
*Note: The electron multipliers have been specifically developed to retrofit the original
manufacturer
’
s equipment. The detector incorporates a modular design to facilitate ease
of replacement and additional innovations intended to enhance performance. First-time
installation requires a mount that includes the mechanical housing. After initial installa-
tion, only the replacement electron multiplier is required.
†This unit is designed for use in the 5975, 5973 GC, and the LC-MSD (not for 5975C Triple
Axis Detector).
Inland 45 Pump Oil
Recommended for most mass spectrometers.
• Ease at cold start.
• Low vapor pressure 10
-7
torr.
• Nontoxic and noncorrosive.
• Compatible with buna-N, neoprene, and
Viton® seals.
• Optimum vacuum pump performance.
• Lowest mass spectrometer background.
• Recommended for optimum mass spec performance.
Rough Pump Oil #19
for MSD Pumps, Oil
Vacuum Pump
• Formulated from crude oil stocks known for
their durability and line-lubricating qualities.
• Use in Agilent 5973/5972/5971 and GCD mass
spec systems, or in other manufacturers’ MSD
systems that require rough pump oil.
• Under average use, the oil in the foreline rough
pump should be replaced every six months.

The Restek GC-MS Cleaning Kit (cat.#s 27194,
27195) Includes:
• Lint-free nylon gloves (small, 2 pair)
• Lint-free nylon gloves (large, 2 pair)
• Lint-free cotton cloth, 9 x 9 (10-pk.)
• Micro mesh 4 x 6 sheet (4-pk.)

• Tool kit bag
Poor sensitivity, loss of sensitivity at high masses, or high mul-
tiplier gain during an auto tune are all indicators that your mass
spectrometer source may need to be cleaned. Restek has assem-
bled all of the necessary components for cleaning and polishing
your ion source.
Reorder Kit (cat.# 27196) Includes:
• Lint-free nylon gloves (small, 2 pair)
• Lint-free nylon gloves (large, 2 pair)
• Lint-free cotton cloth, 9 x 9 (10-pk.)
• Micro mesh 4 x 6 sheet (4-pk.)

For a typical ETP electron multiplier for GC-MS, the total active dynode
surface area is ~1,000 mm
2
. This can be compared to a standard con-
tinuous dynode multiplier that has a total channel surface area of only
around 160 mm
2
(for a channel with 1 mm diameter and 50 mm length).
This increased surface area spreads out the workload of the electron
multiplication process over a larger area, effectively slowing the aging
process and improving operating life and gain stability.
