Safety Information
Use of Gases
The following gases are used with the instrument:
•
Helium (He)
as carrier gas.
•
Oxygen (O
2
)
as gas for sample oxidation.
•
Gases Purity
— The EA IsoLink IRMS System for CNSOH uses helium, argon, and oxygen with
99.995%
minimum purity.
•
Maximum Pressure
— The maximum pressures of the gases to supply the Flash IRMS Elemental
Analyzer is 700 kPa (7 bar).
•
Nominal Pressure of Gases
— The nominal pressure of the gases to supply the Flash IRMS
Elemental Analyzer:
−
Maximum 250-300 kPa (2.5-3 bar) for helium (
He)
.
−
Maximum 250-300 kPa (2.5-3 bar) for oxygen (
O
2
).
Safety Cut Off Device
When an alarm condition is detected, this device cuts off the power to the heating resistors of the
oxidation, reduction furnaces and to the GC Oven. For more details see
WARNING
The instrument must be used according to the specifications of this guide. Improper
use can adversely affect the instrument protection. If the equipment is connected to optional
instruments, such as computer, balance, and so on, the degree of insulation of peripheral devices
should be equivalent or higher (double or reinforced) than that of the EA IsoLink CNSOH IRMS
System. The analyzer operation requires the use of chemical substances having different hazard
specifications.
Before using chemicals, please read the hazard indications and information reported in the Material
Safety Data Sheet supplied by the manufacturer referring to the relevant CAS (Chemical Abstract
Service) number.
