Use of Gases

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.

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
Note ConFlo II/III/IV and IRMS Delta models (TF Bremen manufacturing) use the following
gases:
• Helium (He) as carrier gas and purge gas [CAS number 7440-59-7]
• Carbon Monoxide (CO) as standard gas [CAS number 630-08-0]
• Hydrogen (H
• Nitrogen (N
• Carbon Dioxide (CO
• Sulfur Dioxide (SO

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).
