Laboratory gas cylinder ALPHAGAZ™ 1

gasnitrogencylindrical

Summary
High-purity nitrogen gas suitable for laboratory analyses from % range down to ppm levels.

Applications

• Laboratory analysis: carrier gas (GPC), instrument gas (LC-MS), purge and zero gas, protective atmosphere
• Cryogenic fluid (liquid N2)
• Semiconductor industry: purge gas, inerting, cleaning, CVD carrier gas

DETAILED DESCRIPTION
ALPHAGAZ™ 1 Nitrogen (N2) is a high-purity gas from the ALPHAGAZ™ 1 family. With low levels of critical impurities (moisture, oxygen, hydrocarbons, etc.) and high gas purity, ALPHAGAZ™ 1 products meet or exceed the requirements of most analytical instrument manufacturers. It can be used as a versatile laboratory gas. Cylinder sizes are adapted and available on request. Equipped with a SMARTOP valve for easy opening and with a pressure gauge for internal pressure monitoring.

Advantages

• Simplified selection: laboratory gas for analyses from % range to ppm
• Choice of cylinder sizes according to demand (examples: S11, M20, L50, V09)
• Equipped with SMARTOP valve (easy opening and pressure gauge)

Quality

• Guaranteed critical impurity levels
• Certificate of conformity provided
• Traceability ensured by batch number
• Special pre-treatment of cylinders to guarantee long-term purity and stability

Service

• Product held in stock for availability
• Support from quotation to delivery (expertise center)

Properties and features
Product designed for laboratory analyses from % range to ppm; specification of critical impurities (moisture, oxygen, hydrocarbons) to avoid interferences and equipment contamination. Shelf life: 5 years (60 months). Quality ensured via ISO 9001 certification of laboratories.
