Argon 5.0

Argon 5.0 — Ultra-Clean, Inert Argon for Critical Applications

Argon 5.0 is a high-purity (99.999%) inert gas packaged in high-pressure cylinders for New Zealand labs and industry. It’s designed for analytical instruments, controlled atmospheres, electronics, additive manufacturing and precision welding where background reactivity and trace contaminants must be kept extremely low. As an inert, non-flammable gas, the key risks are pressure and oxygen displacement—see Safety & Handling below.

Typical Uses

• Carrier & purge gas (GC, MS, ICP, FTIR): stable baseline and low background for sensitive detectors.
  

• Gloveboxes & inert atmospheres: protect air- and moisture-sensitive materials in R&D and production.
  

• Electronics / semiconductor tasks: inerting, sputtering, sintering and wafer handling where purity controls yield.
  

• Additive manufacturing / metal 3D printing: chamber purge and build-atmosphere control.
  

• Precision welding (GTAW/TIG, orbital): ultra-clean shielding and back-purging to avoid oxidation and discolouration on high-spec stainless, titanium and nickel alloys.
  
  

If your SOPs require specified limits for O₂, H₂O or THC at ppm/ppb levels, confirm the certificate-of-analysis at order.

Why Choose Coregas NZ for Argon 5.0

• Local NZ supply & delivery for laboratories, universities and high-tech manufacturing.
  

• Cylinder stewardship—return cylinders for refilling or end-of-life processing; tidy compliance for sites.
  

• Process know-how for specifying regulators, purifiers, lines and changeover manifolds.

Product Highlights

• High purity (5.0 / 99.999%) for low background and consistent instrument response.
  

• Chemically inert, non-reactive—ideal as a protective blanket or shield gas.
  

• Stable, dry supply suitable for critical purge/blanket tasks and trace-level work (within grade limits).

Safety & Handling Essentials (Summary)

• Classification: Gas under pressure (compressed); non-flammable, inert.
  

• Primary hazard: Asphyxiation if oxygen is displaced—use only in well-ventilated areas and treat confined spaces with a permit system.
  

• Storage: Cylinders upright and restrained, in a dry, well-ventilated area, below 65 °C, out of direct sun and away from traffic/exits.
  

• Handling: Do not drag/drop/roll; use a rated cylinder trolley. Keep valve protection in place when not connected.
  

• PPE (typical): safety glasses, leather gloves, safety boots for normal handling; respiratory protection if ventilation is inadequate.
  

• Fire: Not combustible; cylinders can rupture if heated—cool from a protected location.
  

• Leaks: Move (if safe) to a well-ventilated remote area; do not attempt to repair valves or safety devices.

Transport & Classification (NZ / International)

• UN 1006 — ARGON, COMPRESSED
  

• Class 2.2 — Non-flammable, non-toxic gas
  

• Typical controls: secure upright in a ventilated vehicle compartment; valves closed and capped; driver briefed on hazards and emergency actions.

Application Notes for Labs & High-Spec Fabrication

• Gas path integrity: use 316L stainless regulators/lines where possible; avoid elastomers or lubricants that outgas.
  

• Purge protocols: slow, stable flow; verify oxygen/moisture break-through before starting runs or welding.
  

• Back-purging (stainless/titanium): use flow-controlled purge dams; allow sufficient dwell before arc start to protect roots.
  

• Instrument baselines: allow instruments to stabilise on Argon 5.0; record baseline noise to detect contamination upstream.
  

Changeover manifolds: consider automatic changeover for uninterrupted supply on long runs.
