Overview
The MCQ GB15K Dynamic Gas Dilution System is an engineered solution for precise, real-time generation of certified gas mixtures across laboratory, calibration, and industrial process environments. Based on mass flow control architecture, the system dynamically blends up to three primary gas streams into a single output stream with continuous, programmable dilution ratios ranging from 1:1 to 1:1000. Unlike static cylinder-based standards, this dynamic approach eliminates cylinder dependency, reduces calibration drift risk, and supports traceable, on-demand gas mixture synthesis under ISO/IEC 17025-compliant workflows. Designed and assembled in Italy, the GB15K integrates high-stability thermal mass flow controllers (MFCs) calibrated to NIST-traceable standards, ensuring reproducible volumetric flow accuracy within ±1% of reading across its full 0–15,000 mL/min per-channel range.
Key Features
- Triple-inlet, single-output architecture optimized for multi-gas blending with independent flow regulation per channel
- Wide dynamic flow range: 0–15,000 mL/min per inlet—suitable for both low-concentration standard generation and high-flow process simulation
- Programmable dilution ratios from 1:1 (undiluted) to 1:1000 (1000× dilution), configurable via front-panel interface or remote command
- Full RS-485 and Ethernet (Modbus TCP) communication protocol support enables seamless integration with LIMS, SCADA, and custom QA/QC software platforms
- Gas compatibility validated for reactive, inert, and flammable species—including H₂, CO, NO, SO₂, and hydrocarbons—under controlled pressure and temperature conditions
- Stainless steel 316 wetted parts and electropolished internal pathways ensure chemical resistance and minimal adsorption for ultra-low-concentration applications
- Integrated leak-check routine and automatic zero-drift compensation enhance long-term operational reliability without manual recalibration
Sample Compatibility & Compliance
The GB15K supports certified gas mixture preparation for regulatory and method-defined applications, including EPA Method TO-14/TO-15, ASTM D6420, ISO 16017-1, and EN 14662. Its MFCs are factory-calibrated against gravimetrically prepared reference standards, with calibration certificates traceable to national metrology institutes (e.g., INRIM, PTB). The system meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). For GLP and GMP environments, optional audit trail logging and user-access controls align with FDA 21 CFR Part 11 data integrity expectations when paired with compliant host software.
Software & Data Management
The GB15K operates natively via a built-in touchscreen HMI supporting intuitive recipe storage, real-time flow monitoring, and alarm logging. For enterprise integration, it exposes all operational parameters—including individual channel setpoints, actual flows, total output concentration, and system status—via Modbus TCP over Ethernet or Modbus RTU over RS-485. No proprietary drivers are required; standard industrial protocols allow direct interfacing with LabVIEW, MATLAB, Python-based automation frameworks, or commercial calibration management systems (e.g., MET/TEAM, QualiCal). All configuration changes and operational events are timestamped and exportable as CSV files for audit-ready documentation.
Applications
- Primary and secondary standard gas generation for GC, GC-MS, FTIR, and electrochemical sensor calibration
- Instrument verification and linearity testing in ambient air monitoring networks (e.g., EEA, US EPA PAMS)
- Dynamic exposure studies in toxicology and inhalation research requiring time-resolved concentration profiles
- Process gas validation in semiconductor fabrication, pharmaceutical cleanroom environmental monitoring, and bioreactor off-gas analysis
- Method development for VOC speciation, greenhouse gas flux measurement, and combustion emissions characterization
- On-site field calibration of portable analyzers used in occupational health and environmental compliance audits
FAQ
What is the maximum number of gases that can be blended simultaneously on the GB15K?
The GB15K supports up to three independent gas inputs, enabling ternary mixture synthesis with fully decoupled flow control.
Is hydrogen (H₂) compatible with this system?
Yes—the GB15K is explicitly validated for H₂ service using stainless steel 316 components and intrinsically safe flow control electronics rated for Class I, Division 1 hazardous locations.
Can the GB15K be integrated into an existing LIMS or MES platform?
Yes—through native Modbus TCP or RS-485 interfaces, the system provides read/write access to all critical parameters without middleware or vendor-specific gateways.
Does the system require annual recalibration?
While not mandatory, MCQ recommends biannual verification using traceable reference gases to maintain ISO/IEC 17025 conformance; onboard diagnostics support self-validation between formal calibrations.
Are custom gas blends pre-programmed or user-defined?
All gas compositions are user-defined via the HMI or external software—no factory presets limit flexibility, and recipes can be saved, recalled, and version-controlled.
