Connecting the Gas Lines
The gas supply lines must be connected to the instrument back panel using the proper inlets and
fittings
.
To connect gas lines
1. Connect the Helium gas line to the inlet marked
He
on the instrument rear panel.
Gas inlet pressure must be set
400-500 kPa
(4-5 bar, 58-73 psig).
2. Connect the Oxygen gas line to the inlet marked
O
2
on the instrument rear panel.
Gas inlet pressure must be set
400-500 kPa
(4-5 bar, 58-73 psig) according to the instrument
configuration.
3. By using the pressure regulators and the pressure gauges located in the detector compartment of
the instrument, set the pressure of the gases as follows:
•
250-300 kPa
(2.5-3 bar) for
helium (He)
•
250-300 kPa
(2.5-3 bar) for
oxygen
(

Electrical Connections
This paragraph explains the electrical connections of the EA IsoLink IRMS System for CNSOH, and
helps you install and configure peripheral devices and Eager
Smart
Data Handling Software.
Mounting Peripheral Devices
Unpack them and follow instructions included with them. Follow the instructions in the paragraphs
below to connect your peripheral devices to the EA IsoLink IRMS System for CNSOH.
CAUTION
The maximum pressures of the gases to supply the Flash IRMS Elemental Analyzer is
700 kPa (7 bar).
CAUTION
The power line and the connections among the instruments must maintain good
electrical grounding. Poor grounding represents a danger for the operator and may seriously affect
the instrument performance.
Do not connect the EA IsoLink IRMS System for CNSOH to lines feeding devices of a heavy duty
nature, such as motors, UV lamps, refrigerators and other devices that can generate disturbances. If
other instruments, such as computer, balance, printer, ans so forth, have to be connected to the
same electrical line as the EA IsoLink IRMS System for CNSOH, ensure that such electrical line is
capable of withstanding such electrical consumptions by calculating the total absorption.
