The EZ No-Vent®
connector incorporates a laser
machined orifice for optimal
flow through the fitting.
Coupled with the 100 μm ID
transfer line, it minimizes the
amount of oxygen entering the
MS, which eliminates the need
for purge gases.
EZ No-Vent® GC Column-Mass
Spectrometer Connector
for Thermo Scientific Focus DSQ
GC Mass Spectrometers
• Change GC/MS columns in
minutes without venting—
100 µm transfer line throttles
vacuum and prevents venting.
• Easy to install and maintain—no special tools or plumbing
required.
• Gold-plated body for inertness.
• Deactivated transfer line keeps analytes focused;
high-temperature polyimide ferrules eliminate leaks at the
problematic transfer line fitting.
• Lower cost than other “no-vent” fittings.
We designed the EZ No-Vent® GC column-mass spectrometer
connector to be simple and easy to use. A critical orifice in the EZ
No-Vent® connector minimizes the amount of oxygen allowed
into the MS source, eliminating the need for purge gas as is
required for other manufacturer’s vent systems. This enables you
to skip the lengthy vent and pump-down cycle otherwise
required when you make a column change. This can save nearly
a day of down-time with each column change. The EZ No-Vent®
connector easily attaches to the MS source without special tools
or extra plumbing.

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.
Other ETP Electron Multipliers are available upon request. Call us if you
do not see your instrument listed.
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.
