ATARICO Angos PLUS Series AGS-P302 Nitrogen Generator

Overview

The ATARICO Angos PLUS Series AGS-P302 Nitrogen Generator is an on-site, continuous-flow gas generation system engineered for laboratory and light industrial applications requiring stable, high-purity nitrogen supply. It employs a dual-tower Pressure Swing Adsorption (PSA) process utilizing high-efficiency zeolite molecular sieve media to selectively adsorb oxygen, moisture, and CO₂ from compressed ambient air—yielding nitrogen with purity adjustable between 97% and 99.9%. Unlike cryogenic or membrane-based alternatives, PSA technology delivers consistent performance across variable demand cycles while maintaining low operational overhead. The AGS-P302 is designed for integration into analytical instrumentation workflows—including LC-MS, GC carrier gas supply, glove box purging, sample preparation inerting, and solvent evaporation systems—where reliability, trace moisture control, and regulatory-compliant documentation are critical.

Key Features

• Stable output of up to 20 L/min at 450 kPa (65 psi), with pressure regulation across 0.1–0.75 MPa to accommodate diverse instrument inlet requirements.
• Adjustable nitrogen purity (97–99.9%) via integrated flow/purity optimization logic; higher purity settings correspond to reduced flow rates per system thermodynamics.
• Dual-tower PSA architecture with automatic valve sequencing ensures uninterrupted nitrogen delivery during regeneration cycles—eliminating downtime or pressure drop spikes.
• Integrated pre-filtration train (coalescing + activated carbon + ultrafine particulate filter) removes oil aerosols, hydrocarbons, and particles <0.01 µm, meeting ISO 8573-1 Class 2:2:2 air quality standards for instrument-grade feed air.
• Dew point consistently maintained between −40 °C and −45 °C, satisfying stringent moisture specifications for mass spectrometry and chromatographic applications.
• Low-noise operation (55 dB[A]) achieved through acoustic enclosure design and vibration-damped mounting—suitable for shared laboratory environments.
• Single-phase 230 V, 50/60 Hz power input with 1.95 kW rated consumption; no external cooling water or exhaust venting required.

Sample Compatibility & Compliance

The AGS-P302 is compatible with all standard nitrogen-dependent laboratory instruments operating within its pressure and flow envelope—including but not limited to Agilent, Thermo Fisher, Waters, and Shimadzu platforms. Its output meets ASTM D6349-20 specifications for instrument-grade nitrogen used in chromatography and spectroscopy. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity), and its electrical safety conforms to GB 4793.1–2019 (equivalent to IEC 61010-1). While not certified for medical or pharmaceutical manufacturing use out-of-the-box, the system supports GLP/GMP-aligned operation when deployed with documented calibration procedures, maintenance logs, and user-defined SOPs. Optional audit-trail-enabled software modules can be configured to meet FDA 21 CFR Part 11 data integrity requirements.

Software & Data Management

The AGS-P302 features an embedded microcontroller with real-time monitoring of critical parameters—including inlet air pressure, tower differential pressure, outlet purity (via internal electrochemical O₂ sensor), dew point, temperature, and runtime hours. All operational data are logged locally with 30-day buffer memory and exportable via USB interface in CSV format. An optional Ethernet/Wi-Fi module enables remote status access and alarm notification (SMTP/SNMP) through a browser-based interface. No proprietary cloud platform is required; raw data files are fully interoperable with LabVantage, STARLIMS, and custom LIMS integrations. Firmware updates are performed offline via signed binary packages to ensure cybersecurity compliance.

Applications

• LC-MS and GC-MS carrier and collision gas supply—replacing high-pressure cylinders with continuous, contamination-free nitrogen.
• Inert atmosphere maintenance for glove boxes, synthesis reactors, and battery material handling environments.
• Nitrogen blow-down and solvent evaporation in sample prep labs (e.g., EPA Method 525.3, ISO 11843).
• Blanketing of reagent storage vessels and HPLC mobile phase reservoirs to prevent oxidation.
• Calibration gas dilution systems requiring stable, low-moisture nitrogen as balance gas.
• Supporting ISO/IEC 17025-accredited testing laboratories seeking traceable, auditable gas sourcing.

FAQ

What is the minimum inlet air quality required for optimal AGS-P302 performance?

Compressed air must be oil-free, dried to ≤−20 °C dew point prior to entry, and filtered to ISO 8573-1 Class 2:2:2. A dedicated refrigerated dryer and coalescing filter upstream are strongly recommended.
Can the AGS-P302 be used for GC carrier gas in regulated pharmaceutical QC labs?

Yes—provided the system is qualified per IQ/OQ protocols, calibrated against NIST-traceable O₂ and dew point analyzers, and operated under documented change control and preventive maintenance schedules.
Does the unit include automatic drainage or require manual condensate removal?

It incorporates an auto-drain solenoid valve synchronized with PSA cycle timing; no manual intervention is needed under normal operating conditions.
Is the nitrogen purity verified in real time?

An integrated electrochemical oxygen sensor provides continuous O₂ concentration measurement (0–1000 ppm range, ±5% accuracy), enabling live purity estimation and alarm triggering if thresholds are exceeded.
What service intervals are recommended for molecular sieve replacement?

Under typical lab usage (8 hrs/day, 5 days/week), zeolite beds maintain specification performance for ≥36 months; replacement is condition-based and confirmed via O₂ breakthrough testing during annual PM.
