LD8000

Online trace Nitrogen in argon,
Helium and Crude Argon analyzer

The LD8000 is an online analyzer to monitor trace N2 in Ar/He/Crude Argon. Plasma emission detector is used to selectively measure trace N2 in Argon or/and Helium bulk gases. The analysis of trace N2 in Neon, Xenon and Krypton can also be realized.
