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
