Gas Specifications
**
Any gas including He which has an ionization potential greater than 12 eV
**
Any gas including He which has an ionization potential greater than 11 eV
Purity Specifications
• Helium (discharge and carrier gas) must have a minimum purity of
99.999%, with < 20 ppm Ne impurity. For trace analysis of fixed gases,
we strongly recomment 99.9999% purity He with < 0.5 ppm Ne.
• Ar-PDPID mode: 2% ± 0.2% Ar in 99.999% He balance
• Kr-PDPID mode: 1.5% ± 0.1% Kr in 99.999% He balance
• Xe-PDPID mode: 0.8% ± 0.2% Xe in 99.999% He balance
