ETP Electron Multipliers
for Mass Spectrometry
• Air stable.
• 2-year shelf life guarantee.
• Discrete dynode design
results in extended
operating life.
The multi-dynode approach
of all ETP multipliers results
in longer lifetimes and better
sensitivities compared with channel
multipliers because of greater surface area.
The electron multipliers manufactured by ETP use a proprietary
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 exceptional gain
to be achieved from each dynode. This material is also very sta-
ble in air. In fact, an ETP multiplier can be stored for years before
being used. As a direct result of the high stability of the active
materials used in ETP multipliers, they come with a 2-year shelf
life warranty (stored in original sealed package). Many testing
laboratories take advantage of this long shelf life by keeping a
replacement ETP multiplier on hand, ready for immediate instal-
lation. This keeps the instrument downtime to a minimum.

Replacement Interface Guide Tube
for Agilent 5971/5972 MS
• Meets or exceeds manufacturer’s performance.
• Made of high-quality stainless steel.
Replacement Cold Sensor
for Agilent 5971/5972 MS Diffusion Pump
• Meets or exceeds manufacturer’s performance.
• Made of high-quality stainless steel.
*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 which includes the mechani-
cal housing. After initial installation, only the replacement electron multiplier is
required.
†This unit is designed for use in the 5975, 5973 GC and the LC/MSD.

did you
know
?
A typical ETP electron multiplier has a total active dynode surface area
of ~1,000 mm
2
compared to a standard continuous dynode multiplier
that only has a total channel surface area of around 106 mm
2
. The
increased surface area of the ETP slows the aging process and
improves operating life.
