2 Introduction to the Chip Cube
Introduction
The Chip Cube Interface Assembly
The Chip Cube Interface Assembly is effectively a spray chamber for use with
the Chip Cube. For troubleshooting purposes, a fused silica sprayer needle can
be fitted to a holder bracket. This allows to generate a nano spray without
Chip Cube.
The Chip Cube Interface Assembly is attached to the MS in the usual way with
two hinges. Two slotted holes in the interface accept the retaining pins of the
Chip Cube. For maintenance purposes, the Chip Cube can be easily detached
from the spray chamber and moved backwards. The spray chamber can then
be opened to allow easy access to the MS inlet for maintenance.
LED illumination and a black and white CCD camera provide a convenient
way of monitoring the nanospray performance on an external monitor.
Details about the Chip Cube Interface Assembly and operating parameters of
the connected mass spectrometer can be found in the Chip Cube Interface
Assembly guide.

Power Switch

The Chip Cube power switch is located on the lower left front side. The button
is fitted with a green indicator light that stays on as long as the Chip Cube is
powered up.
Even with the front power switch turned off, parts of the Chip Cube electronics stay
WA R N I N G
energized. To disconnect the instrument completely from line power, unplug the power
cord.
There is no main power switch on the spray chamber. An external 9V DC
power supply connects to a low voltage power manifold on the lower front side
of the spray chamber. The CCD camera plugs into the second socket of the
spray chamber mount. 5V DC for the illumination are generated by a voltage
regulator on the power distribution board attached to the spray chamber
mount.

• Extract the sprayer tip from the chip holder.
• Position the sprayer tip reproducible in front of the MS inlet.
• Provide two independent, concentrically high pressure nano flow valves.
