Mechanical Pump Oils
W
henever selecting mechanical pump fluids for use in
mass spectrometers, it is important to select the fluid
with the lowest vapor pressure. The vapor pressure
of the oil is important because it determines the ultimate vacuum
the pump can achieve. Lower vapor pressures will allow the user to
minimize backstreaming, significantly reduce pumpdown time and
maximize vacuum. The major mineral based oils used for rough
pumps in mass spectrometers include Inland 19, Invoil® 20, Inland
33 and Inland 45. Any of these pump fluids can be used in all
Edwards, Adixen, Welch and other mechanical rough pumps.

The selection of a specific grade of pump oil utilized depends on the
users needs including the mass range of the mass
spectrometer, the system cleanliness required, the sensitivity
required and the cost the user is willing to pay.
Inland 19
is the basic mineral oil used in most mass spectrometer
vacuum pumps. It has been engineered for use with all mechanical
vacuum pumps, providing for minimal backstreaming.
Invoil 20
is a better grade of mineral oil for use in mechanical
rough pumps. It has been distilled to remove the majority of the light
fractions present in the base oil. These light fractions represent
weak links in oil and tend to provide a source of attack for reactive
gases. In addition
they can easily migrate into the vacuum system
to increase mass spec background. Invoil 20 will provide for better
pumping efficiency, lower vacuum and longer vacuum pump life in
comparison to Inland 19 or similar oils.
Inland 33
is manufactured to enhance the oxidation resistance of
the fluid providing outstanding chemical stability.
The process also
provides a clear oil base virtually free of impurities. This oil is equiv-
alent to the P3 rough pump oil used in Pfeiffer pumps.
Inland 45
is the newest and best grade of oil for mechanical vac-
uum pumps for mass spectrometers. It is a highly refined and dis-
tilled pump oil which will provide for optimum vacuum levels and
minimal mass spectrometer background. It is recommended for
mass spectrometers such as high resolution instruments which
require the cleanest system, highest vacuum levels and optimum
pumping efficiency. This oil is now recommended for the Agilent
mass spectrometer systems.
Inland TW
mechanical pump fluid is specifically recommended for
applications where exposure to reactive or corrosive gases is
prevalent, such as electrospray and particle beam.
Fomblin PFPE
oils are non-flammable chemically inert fluids for
use in areas where there are high levels of oxygen or where
serious corrosion is a problem. This oil is identical to Krytox.
Several manufacturers recommend this pump fluid for uses such as
in the Agilent Particle Beam mass spectrometer.
