ATARICO Angos PLUS Series Nitrogen Generator AGS-P602

Overview

The ATARICO Angos PLUS Series Nitrogen Generator AGS-P602 is an on-site, continuous-flow nitrogen supply system engineered for laboratory and light industrial applications requiring reliable, high-purity gaseous nitrogen without reliance on high-pressure cylinders or liquid nitrogen dewars. It employs a dual-bed Pressure Swing Adsorption (PSA) process utilizing high-efficiency zeolite molecular sieve media to selectively adsorb oxygen, moisture, CO₂, and other trace gases from compressed air—yielding a stable nitrogen stream with purity programmatically adjustable between 97% and 99.9%. The system is designed for integration into analytical instrumentation (e.g., LC-MS, GC carrier gas, ICP-MS purge), inert atmosphere glove boxes, sample preparation enclosures, and QA/QC testing environments where consistent gas quality, operational safety, and long-term cost control are critical.

Key Features

• Stable, continuous nitrogen output at 40 L/min @ 65 psi (4.5 bar), with pressure regulation across 0.1–0.75 MPa to accommodate diverse instrument inlet requirements.
• Adjustable purity control: higher purity (up to 99.9%) achievable at reduced flow rates; real-time monitoring of O₂ residual content is supported via optional integrated electrochemical sensor (not standard).
• Deep-dry nitrogen delivery with dew point consistently maintained between −40 °C and −45 °C, meeting ISO 8573-1 Class 2.2.1 (solid particle, water, oil) for critical dry-gas applications.
• Integrated multi-stage air pretreatment: coalescing filter (0.01 µm particulate removal), desiccant dryer, and activated carbon polishing stage ensure feed air meets PSA bed inlet specifications and extends molecular sieve service life.
• Robust industrial-grade architecture: stainless steel pneumatic manifolds, ASME-certified pressure vessels, IP54-rated electrical enclosure, and vibration-damped mounting for 24/7 operation in shared lab environments.
• Low acoustic signature (58 dB(A) at 1 m) and compact footprint (1200 × 600 × 1300 mm) enable installation in proximity to sensitive instrumentation or within centralized utility rooms.

Sample Compatibility & Compliance

The AGS-P602 is compatible with all standard nitrogen-dependent laboratory equipment requiring Grade 5 (99.999%) or lower purity—particularly suitable for instruments accepting 99.5% or 99.9% nitrogen, including but not limited to gas chromatographs (GC), nitrogen blow-down evaporators, FTIR purge systems, thermal analyzers (TGA/DSC), and elemental analyzers. Its performance aligns with key international standards governing compressed gas quality and laboratory gas generation, including ISO 8573-1:2010 (compressed air purity classes), ASTM D6349 (standard guide for gas purity in analytical applications), and USP 〈41〉 (balance calibration gases). While the unit itself does not carry CE, UL, or UKCA certification, its electrical design conforms to IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity). For regulated GxP environments, optional audit-trail-enabled PLC logging and 21 CFR Part 11-compliant software modules are available upon request.

Software & Data Management

The AGS-P602 operates via an embedded industrial PLC with a 5.7-inch TFT HMI interface supporting multilingual navigation (English, Chinese, Spanish). Core parameters—including real-time flow, outlet pressure, purity estimate (based on flow/pressure correlation model), inlet air dew point, and system fault codes—are continuously displayed and logged locally with 30-day circular memory. Optional Ethernet/IP or Modbus TCP connectivity enables integration into LabVantage, STARLIMS, or custom SCADA platforms for centralized monitoring, remote alarm notification (email/SMS), and automated data archival. All operational logs include timestamp, operator ID (if configured), and event severity classification—supporting GLP/GMP documentation requirements when paired with validated electronic record procedures.

Applications

• LC-MS and GC-MS carrier and nebulizer gas supply (99.5%–99.9% purity range)
• Inert blanketing for solvent evaporation, sample storage, and reagent handling
• Calibration gas dilution systems requiring stable, low-moisture N₂
• Environmental test chambers and accelerated aging ovens
• Pharmaceutical stability studies (ICH Q1–Q5 compliant inert atmospheres)
• Electronics manufacturing: solder paste reflow protection and component passivation

FAQ

What maintenance intervals are recommended for the AGS-P602?
Pre-filters require replacement every 3,000 operating hours or annually (whichever occurs first); molecular sieve beds are rated for ≥30,000 hours under specified inlet air conditions (≤−20 °C dew point, <0.1 ppm oil aerosol). Full preventive maintenance—including valve actuator inspection and pressure decay verification—is advised biannually.

Can the AGS-P602 be integrated with existing lab air compressors?
Yes—provided the compressor delivers clean, dry, oil-free air at ≥6.5 bar (94 psi) and ≥60 L/min free air delivery (FAD), with ISO 8573-1 Class 2.2.1 pre-treatment (or equivalent filtration/drying upstream of the generator).

Is nitrogen purity verified in real time?
The base configuration uses flow/pressure-based purity estimation. A factory-installed, NIST-traceable paramagnetic O₂ analyzer (0–1,000 ppm range, ±2% FS accuracy) is available as an upgrade for direct, continuous purity validation.

Does the unit support automatic start/stop based on demand?
Yes—via dry-contact input (0–10 V or 4–20 mA signal) or Modbus command, enabling synchronization with instrument power states or central building management systems.

What is the expected lifetime of the molecular sieve under typical lab use?
With compliant inlet air quality and adherence to scheduled maintenance, zeolite media typically maintains >95% of initial adsorption capacity for 8–10 years—verified by annual performance validation protocols outlined in the user manual.
