Use of Gases
Gas Supply
The Flash IRMS Elemental Analyzer uses the following gases:
• Helium (He) as carrier gas and purge gas [
CAS number 7440-59-7
]
• Oxygen (O
2
) as gas for sample oxidation [
CAS number 7782-44-7
]
Gas Purity
The EA IsoLink IRMS System for CNSOH requires the use of ultra-high purity gas chromatography
grade (99.999%) gases.
Maximum Pressure
The maximum pressure of the Elemental Analyzer gas supplies is 700 kPa (7 bar).
Hot Surface Label
CAUTION
Before using gases, carefully read the hazard indications and information reported in the
Material Safety Data Sheet (MSDS) supplied by the manufacturer referring to the CAS (Chemical
Abstract Service) number.
It is the your responsibility to see that all local safety regulations for the use of gases are obeyed.
