Trace Impurity Analyzers

Trace Impurity Analyzers continuously measure low-level contaminants in high-purity and process gases without a full chromatographic separation. Products in this category include LDetek LD8001 trace nitrogen analyzers, LD8001+ and LD8001+Ar ppb analyzers for ultra-pure argon and helium, the LD8001-FID total hydrocarbon analyzer, the LD8001-TCD binary gas analyzer, the LD8001MG multi-impurity analyzer, and LDMOX and LDSENZ compact moisture, oxygen and nitrogen analyzers.

Measurement technologies include plasma emission, flame ionization, thermal conductivity, quartz-crystal and ceramic moisture sensing, and electrochemical or zirconia oxygen sensing.

Applications include:

• Trace nitrogen in argon, helium and crude argon
• Trace argon in ultra-pure helium
• Total hydrocarbon monitoring in pure gases
• Moisture and oxygen checks on gas supply lines
• Continuous purity monitoring in gas production and distribution
