Hiden QIC 20 Compact Online Gas Analysis Mass Spectrometer

Overview

The Hiden QIC 20 Compact Online Gas Analysis Mass Spectrometer is a benchtop quadrupole mass spectrometer engineered for real-time, high-fidelity gas-phase composition monitoring in dynamic industrial and laboratory environments. Based on electron ionization (EI) with optional soft ionization capability (e.g., low-energy electron impact), the system operates on the principle of mass-to-charge ratio (m/z) separation within a robust RF/DC quadrupole mass filter. Its direct capillary inlet—constructed from heated, inert fused quartz—enables rapid, contamination-free transfer of reactive, condensable, or trace-level gaseous species into the high-vacuum ion source (<1×10⁻⁶ mbar). Designed for continuous process integration rather than discrete batch analysis, the QIC 20 delivers sub-second temporal resolution (<300 ms system response time), making it suitable for closed-loop feedback control, transient reaction profiling, and time-resolved emission monitoring.

Key Features

• Inert, temperature-controlled quartz inlet capillary (up to 200 °C), minimizing surface adsorption, catalytic decomposition, or memory effects during analysis of corrosive, polar, or reactive gases (e.g., NH₃, HCl, silanes, metal organics)
• Automated pressure-regulated sampling: maintains stable ion source pressure across variable process line pressures (100 mbar – 2 bar standard; extended range options available up to 30 bar with high-pressure interface)
• High-sensitivity detection: standard limit of detection at 0.1 ppm for common diatomic and small organic molecules; enhanced sensitivity down to 5 ppb achievable via optional low-noise electronics and cryogenic background suppression
• Modular mass range configuration: base 1–200 amu coverage supports most inorganic and light organic volatiles; optional extended ranges (up to 510 amu) accommodate heavier organometallics, catalyst ligands, and decomposition fragments
• Integrated liquid nitrogen-cooled cryopanel (optional): reduces partial pressure of condensable background species (e.g., H₂O, hydrocarbons, solvents), improving signal-to-background ratio and long-term vacuum stability
• Real-time quantitative operation: MASsoft software enables multi-point calibration, isotopic abundance correction, and linear dynamic range extension (>6 decades) using internal reference gases and stored response factors

Sample Compatibility & Compliance

The QIC 20 accommodates a broad spectrum of gas-phase samples without pre-concentration or derivatization—including corrosive etchants (Cl₂, F₂, NF₃), metalorganic precursors (TMAl, DEZ), combustion byproducts (CO, NOₓ, unburnt hydrocarbons), and ambient air contaminants. Its all-metal, electropolished vacuum path and chemically inert sampling train comply with ISO 14644-1 Class 5 cleanroom compatibility requirements when installed with appropriate filtration and purge protocols. For regulated environments, MASsoft supports audit-trail logging, user-access controls, and electronic signature workflows aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations. System validation documentation—including IQ/OQ templates and performance qualification protocols—is provided to support GLP and GMP-aligned deployment in pharmaceutical, semiconductor, and catalyst manufacturing settings.

Software & Data Management

Control, calibration, and data interpretation are unified within MASsoft Professional—a Windows-based application developed specifically for Hiden mass spectrometers. The software provides simultaneous multi-channel acquisition (up to 128 m/z traces at 10 Hz), real-time background subtraction, and automated peak deconvolution for overlapping species (e.g., CO₂ vs. N₂O at m/z 44). Quantitative methods are defined via customizable calibration curves (linear, quadratic, or polynomial), with support for internal standard normalization and drift compensation algorithms. All raw and processed data are stored in vendor-neutral HDF5 format, enabling seamless export to LIMS, SCADA, or MATLAB/Python for advanced statistical modeling. Remote monitoring and alarm-triggered data capture are supported via TCP/IP and OPC UA interfaces.

Applications

• Chemical vapor deposition (CVD) and metalorganic CVD (MOCVD) endpoint detection and precursor decomposition monitoring
• Catalytic reaction studies: real-time tracking of intermediate formation, selectivity shifts, and deactivation kinetics under varying T/P conditions
• Thermal analysis coupling (TGA-MS, DSC-MS): identification of evolved gases during polymer degradation, battery electrolyte decomposition, or pharmaceutical excipient stability testing
• Environmental emissions monitoring: continuous measurement of fugitive VOCs, NOₓ, SO₂, and halogenated compounds from stack or fenceline sources
• Process safety: detection of trace hydrogen, methane, or oxygen breakthrough in inerted reactors or glovebox atmospheres
• Contaminant forensics: identification of residual solvents, cleaning agents, or outgassed plasticizers in ultra-high-purity gas delivery systems

FAQ

What vacuum level does the QIC 20 require for stable operation?

The instrument maintains optimal sensitivity and mass resolution under a base pressure of ≤1×10⁻⁶ mbar in the analyzer region, achieved via integrated turbomolecular pumping and optional cryo-assisted background reduction.
Can the QIC 20 be integrated into an existing PLC-controlled process line?

Yes—via RS485 Modbus RTU or Ethernet/IP protocols, the system supports bidirectional communication with industrial controllers for automated start/stop, alarm relay outputs, and setpoint-driven sampling logic.
Is method transfer possible between different QIC models or laboratories?

MASsoft-generated method files (.msm) are fully portable across QIC-series instruments; spectral libraries and calibration databases are exportable in CSV and XML formats for cross-platform reproducibility.
How often does the filament require replacement under continuous operation?

Standard rhenium filaments exhibit >6,000 hours of operational life under typical EI conditions; extended-life iridium filaments are available for applications involving highly reactive or oxidizing matrices.
Does the system meet ATEX or IECEx certification for hazardous area installation?

The QIC 20 is designed for safe zone installation (Zone 2 / Class I Div 2); explosion-proof enclosures and intrinsically safe signal interfaces are available as certified OEM options through Hiden’s authorized system integrators.
