Overview
The MICHEM MY Series Argon Purifier is an engineered gas purification system designed for continuous, on-site upgrading of commercial-grade argon (≥99.9% purity) to ultra-high-purity argon (≥99.9999%, also designated as “6N” grade). It employs a multi-stage purification architecture combining solid-state catalytic conversion, nano-structured physical adsorption, and selective chemical reaction—eliminating nitrogen, oxygen, carbon monoxide, carbon dioxide, methane, and moisture without requiring external hydrogen addition or process interruption. Unlike conventional tower-based purifiers relying on cryogenic or pressure-swing adsorption, the MY Series utilizes a proprietary regenerable synthesis reactor built with imported noble-metal catalysts and sub-100 nm functionalized adsorbent media. This design enables stable, long-duration operation under industrial flow conditions (1–4 m³/h), making it suitable for analytical instrumentation demanding stringent gas integrity—including ICP-OES, ICP-MS, GD-MS, GC carrier gas supply, semiconductor chamber purge, single-crystal silicon growth, and high-temperature metallurgical inerting.
Key Features
- Regenerable synthesis reactor with noble-metal catalysts and nano-adsorbent matrix—enables in-situ, fully automated regeneration without shutdown or H₂ co-feed
- Continuous high-purity argon output during regeneration cycles—no interruption to downstream instruments or processes
- Dual-stage particulate filtration: stainless-steel sintered filters (≤6 µm particle retention) installed at both inlet and outlet manifolds
- High-integrity fluid path: all wetted components constructed from electropolished 316L stainless steel tubing and VCR-compatible valves
- Integrated pressure regulation and monitoring: adjustable inlet pressure control (0.2–1 MPa) with real-time digital display and overpressure safety cutoff
- Energy-efficient operation: 2.2 kW nominal power draw with thermal management optimized for 24/7 duty cycle reliability
- Compact footprint (500 × 500 × 900 mm) and lightweight chassis (48 kg)—designed for benchtop or rack-mounted deployment in constrained lab or cleanroom environments
Sample Compatibility & Compliance
The MY Series is compatible with standard commercial argon supply cylinders (CGA-580) and pipeline-fed bulk argon systems delivering ≥99.9% base purity. It meets the performance requirements specified in GB/T 4842–2006 (“Argon”) for Grade 6N (99.9999%) product gas, with verified residual impurity levels: N₂ ≤ 0.2 ppm, O₂ ≤ 0.3 ppm, CO/CO₂/CH₄ ≤ 0.2 ppm each, and dew point ≤ −80 °C. While not certified to ISO 8573-1 Class 0 for compressed air, its validated output complies with the gas quality prerequisites of ASTM E1444 (magnetic particle testing), ASTM E1019 (O/N/H analysis), and USP for chromatographic carrier gases. The unit supports GLP/GMP-aligned operational traceability when integrated with optional data logging modules.
Software & Data Management
The KMK-Y-I operates via a dedicated embedded controller with a 4.3-inch TFT touchscreen interface. All critical parameters—including inlet/outlet pressure, internal reactor temperature, cumulative runtime, and regeneration cycle count—are logged locally with timestamped records retained for ≥12 months. Optional RS-485 Modbus RTU or Ethernet TCP/IP communication allows integration into centralized facility monitoring systems (e.g., LabVantage, DeltaV, or custom SCADA). Audit trails comply with FDA 21 CFR Part 11 requirements when paired with user-authenticated access control and electronic signature modules (sold separately). No cloud connectivity or proprietary SaaS platform is required for core functionality.
Applications
- ICP-OES and ICP-MS plasma stabilization and nebulizer gas supply
- Carrier and make-up gas for GC-FID, GC-TCD, and GC-MS systems
- Purge and protective atmosphere in XRF sample chambers and spark emission spectrometers (e.g., OES, GD-OES)
- Inert blanket gas for molten metal handling, titanium alloy welding, and rare-earth metal refining
- Process gas in CVD/PVD semiconductor fabrication tools and epitaxial silicon growth furnaces
- Zero-air generator feedstock conditioning where ultra-low N₂/O₂ background is essential
FAQ
Does the MY Series require hydrogen for regeneration?
No. Regeneration is achieved via controlled thermal cycling and vacuum-assisted desorption—no external H₂ source or flammable gas handling is involved.
Can the unit operate continuously while regenerating?
Yes. The dual-reactor architecture ensures uninterrupted high-purity argon delivery during full regeneration cycles.
What is the expected service life of the synthesis reactor?
Under typical usage (≤8 h/day, 5 days/week), the reactor maintains ≥99.9999% purity for ≥18 months before scheduled replacement; lifetime extends significantly with periodic regeneration and proper inlet filtration.
Is the system compatible with non-Chinese analytical instruments?
Yes. Standard CGA-580 and ISO 8573-7 quick-connect fittings are supported; custom adapter kits are available for Thermo Fisher, PerkinElmer, Agilent, Shimadzu, and Bruker OEM interfaces.
How is compliance with analytical instrument gas specifications verified?
Each unit ships with a factory calibration certificate referencing traceable gas chromatographic analysis (per GB/T 4842–2006 Annex B), including full impurity speciation report.
