Overview
The ATARICO ATEN-P602 is an engineered dual-stream gas generation system designed specifically for liquid chromatography–mass spectrometry (LC-MS) laboratories requiring concurrent, stable supplies of high-purity nitrogen and clean, dry compressed air. Unlike conventional single-output nitrogen generators, the ATEN-P602 integrates a pressure-swing adsorption (PSA) nitrogen module with a dedicated, oil-free air compression and drying subsystem—both housed within a unified, vibration-isolated chassis. The system operates on the principle of selective adsorption of oxygen, carbon dioxide, and moisture by high-efficiency zeolite molecular sieves under controlled pressure cycles, enabling continuous nitrogen separation from ambient air. Simultaneously, the integrated air path delivers ISO 8573-1 Class 2:2:2 compressed air (≤0.1 µm particles, ≤0.1 mg/m³ oil aerosol, dew point ≤−40 °C), eliminating dependency on external oil-lubricated compressors or separate desiccant dryers. This architecture ensures long-term operational stability, reduced thermal drift in sensitive MS ion sources, and compliance with instrument OEM gas specifications for electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI).
Key Features
- Integrated dual-gas architecture: Independent PSA nitrogen generation and purified air delivery in one compact unit—no external air compressor required.
- Multi-chamber thermal isolation design: Separates heat-sensitive molecular sieve beds from compressor heat, extending sieve life and maintaining consistent purity across temperature fluctuations (5–35 °C ambient).
- Multi-point PLC control system: Manages pressure sequencing, cycle timing, valve actuation, temperature monitoring, and real-time fault diagnostics—including overcurrent and leakage protection per IEC 61000-4-5.
- Optimized adsorption dynamics: Proprietary cycle programming increases nitrogen recovery efficiency by 25–40% versus equivalent-capacity membrane systems, reducing specific energy consumption to ≤112 kWh/kg N₂ at 99% purity.
- 24/7 continuous operation capability: Rated for unattended, year-round use under GLP-compliant laboratory conditions; validated mean time between failures (MTBF) >12,000 hours.
- Low-noise mechanical design: Acoustic enclosure and anti-vibration mounting limit operational noise to 56 dB(A) at 1 m—suitable for shared lab environments.
Sample Compatibility & Compliance
The ATEN-P602 meets gas quality requirements for major LC-MS platforms including Thermo Fisher Scientific (Orbitrap, TSQ series), Waters (Xevo, Vion), Agilent (6470, 6550), and SCIEX (TripleTOF, QTRAP). Its nitrogen output complies with ASTM D6349-20 (for purity verification) and ISO 8573-1:2010 Class 2 for particulates and water content. The integrated air stream satisfies ISO 8573-1:2010 Class 2:2:2, ensuring compatibility with pneumatic nebulizers and curtain gas inlets. All electrical components conform to CE, RoHS, and UL 61010-1 safety standards. The system supports audit-ready operation under FDA 21 CFR Part 11 when paired with optional data logging software featuring electronic signatures and immutable event timestamps.
Software & Data Management
While the ATEN-P602 operates via intuitive front-panel controls (one-button start/stop), optional Ethernet-enabled firmware enables remote monitoring via web-based HMI. Real-time parameters—including nitrogen purity (via internal electrochemical O₂ sensor), outlet pressure, dew point, and compressor runtime—are logged at user-defined intervals (1–60 min) and exportable as CSV or PDF reports. Event logs record all critical alarms (e.g., sieve saturation warning, filter clogging, pressure deviation >±5%), supporting preventive maintenance scheduling and GLP/GMP traceability. Audit trail functionality complies with ALCOA+ principles, recording operator ID, timestamp, action taken, and system state before/after each intervention.
Applications
- LC-MS mobile phase nebulization and desolvation gas (nitrogen)
- LC-MS curtain gas and collision gas (high-purity nitrogen)
- Pneumatic assistance for ESI and APCI source operation (clean dry air)
- Blank solvent purging and instrument standby purge protocols
- Gas supply for nitrogen-sealed glove boxes used in sample preparation
- Backup or primary gas source in centralized lab gas distribution networks
FAQ
Does the ATEN-P602 require external cooling or ventilation?
No. The system incorporates passive thermal management and requires only 30 cm clearance on all sides for ambient air convection. No chilled water or HVAC ducting is needed.
Can nitrogen and air outputs be used simultaneously at full rated flow?
Yes. Both streams operate independently with no cross-interference; simultaneous 30 L/min N₂ @ 65 psi and 48 L/min air @ 65 psi are fully supported without derating.
What maintenance intervals are recommended?
Pre-filters: every 6 months | Coalescing filters: annually | Molecular sieve cartridges: 24,000 operating hours (≈3 years at 8 h/day) | Full system calibration: biannually.
Is the system compatible with third-party LC-MS software integration?
Yes. Modbus TCP and OPC UA protocols are available via optional communication module for integration into LabVantage, STARLIMS, or custom SCADA environments.
How does the ATEN-P602 handle altitude variations?
Performance is rated up to 1500 m ASL. Above this elevation, nitrogen flow and purity may decrease linearly (~0.8% purity loss per 300 m); consult factory for high-altitude configuration options.
