Model 3480 Electrospray Aerosol Generator
A n a l o g O u t p u t
The Electrospray has a single 15-pin, D-subminiature connector
port on the back panel labeled ANALOG OUTPUT that can be used
to measure signals that represent the voltage and current output
on the front panel meters of the instrument. See
for a
detailed list of the signal connections.
F i l t e r e d A i r I n p u t
The back panel of the Electrospray has an input marked FILTERED
AIR IN, 25 PSI MAX that is a ¼” Swagelok
tube fitting with nylon
ferrules. Insert the supplied polyethylene tubing or a similar tubing
and tighten the Swagelok® nut finger-tight plus ¼-turn with a
wrench. This will provide a secure connection and allow the tubing
to be removed without damaging the ferrules. A regulated,
compressed air supply that furnishes HEPA-filtered, clean, dry air
must be used to supply filtered air to the Electrospray. TSI
Model 3074B Filtered Air Supply is recommended and may be
purchased separately. The recommended pressure of the filtered air
supply used with the Electrospray is 15 psi.

W A R N I N G
Supplying more than 25 PSI air pressure could result in damage to the
internal components of the Electrospray and decreased sensitivity of the
pressure regulator and air rotameter.

Above the filtered air input, is an identical input marked CO
2
IN,
15 PSI MAX. Connect the supplied polyethylene tubing in the
manner described for the Filtered Air Input, using a commercial
CO
2
compressed gas tank to supply CO
2
to the Electrospray.
Commercial CO
2
tanks and accessories are available from most
compressed gas suppliers, in denominations ranging from 2.5 to
50 lb. The recommended pressure of the CO
2
supply used with the
Electrospray is 5 psi.
