Nitrogen nitrogen generator HF series

dryhigh-puritylaboratory

Overview
Laboratory nitrogen generators produce high‑purity nitrogen on‑site for analytical applications. The HF series (e.g. HF30A) delivers up to 99.5% purity and is optimized for LC‑MS, where a stable nitrogen supply is essential for reproducible results. Dürr Technik, together with partner Chromalytic, combines premium compressors with modern control and treatment components to provide turnkey solutions.

Benefits of on-site generation

• Independence from cylinder gas suppliers
• Consistent nitrogen quality for reliable analyses
• Lower operating costs and improved workplace safety
• Production sized to demand, minimising waste

Integrated compressor models (e.g. HF30A / HF30P)

• Oil‑free premium compressor with advanced control
• All‑in‑one solution for labs without central compressed air
• Internal buffer tank for immediate nitrogen availability
• Optimised for modern LC‑MS systems and continuous operation

Compressorless models (e.g. HF30N / HF60N)

• Designed for laboratories with central compressed air supply
• Efficient nitrogen separation to reduce air consumption
• Compact design for bench or under‑bench installation
• Integrated nitrogen storage and three‑stage filtration

LC‑MS optimized models (MG)

• HF30N‑MG / HF60N‑MG: combined nitrogen and dry air supply
• Designed for instruments such as Sciex, Bruker and Shimadzu
• Continuous, very quiet operation
• Production matched to consumption on site

Applications

• LC‑MS analysis
• Pharmaceutical and chemical analysis
• Food analysis (e.g. acrylamide determination)
• Research & development and sample preparation
• Thermogravimetry and quality control

Dürr Technik advantages

• Low total cost of ownership
• Oil‑free, low‑maintenance technology
• High operational reliability for mission‑critical applications
• Compact footprint for easy integration
• Consulting, customisation, installation and support services
