Overview
The WAYEAL High-Capacity Direct-Pressure Helium Mass Spectrometer Leak Detector is a dedicated residual gas analysis system engineered for quantitative detection and localization of minute helium tracer gas ingress in pressurized components. Operating on the principle of magnetic sector or quadrupole mass spectrometry, it selectively ionizes helium atoms (mass-to-charge ratio m/z = 4) and separates them from background atmospheric gases—including nitrogen (m/z = 28), oxygen (m/z = 32), and water vapor (m/z = 18)—via high-resolution mass filtering. Unlike vacuum-chamber-based sniffing or accumulation methods, this instrument employs direct-pressure testing: the test object is pressurized with helium-enriched gas (typically 5–100% He in N₂ or air), while the detector’s mass spectrometer inlet is coupled to a calibrated leak port or sealed test fixture. This configuration enables rapid, high-throughput evaluation of large-volume or high-surface-area assemblies—such as automotive EV battery enclosures, HVAC heat exchangers, medical device housings, and semiconductor process chambers—without requiring evacuation of the entire test volume.
Key Features
- High-capacity pressure-rated test interface compatible with up to 1.6 MPa (232 psi) internal test pressure, supporting ISO 15497-compliant burst and endurance verification protocols.
- Dual-mode operation: configurable for either quantitative leak rate measurement (in Pa·m³/s or atm·cm³/s) or pass/fail threshold-based go/no-go testing with user-defined alarm limits.
- Integrated helium recovery circuitry minimizes operational helium consumption by recirculating and purifying carrier gas through a heated getter and cold trap assembly.
- Robust quadrupole mass filter with <1.0 amu resolution ensures stable m/z = 4 peak discrimination under varying ambient humidity and temperature gradients (operating range: 10–40 °C, ≤80% RH non-condensing).
- Modular vacuum architecture featuring dual-stage pumping: a dry scroll backing pump paired with a turbomolecular pump (≥300 L/s at N₂) delivers base pressures below 5×10⁻⁷ mbar in less than 90 seconds.
- Front-panel touchscreen HMI with multi-language UI (English, German, Japanese, Simplified Chinese) and embedded diagnostics for real-time ion source health monitoring and pump status logging.
Sample Compatibility & Compliance
The detector accommodates rigid and semi-rigid test objects ranging from 0.1 L to 20,000 L internal volume, including welded stainless steel vessels, aluminum die-cast housings, polymer-sealed connectors, and laminated pouch cells. Fixture interfaces conform to ISO 20486 (leak testing terminology) and ASTM E493 (standard practice for helium mass spectrometer leak testing). The system supports GLP/GMP-aligned audit trails when connected to external SCADA or MES platforms via Ethernet/IP or Modbus TCP. All firmware and calibration routines comply with ISO/IEC 17025 traceability requirements, with factory calibration certificates issued per ISO 17025-accredited reference standards (e.g., NIST-traceable calibrated leaks at 1×10⁻⁶, 1×10⁻⁷, and 1×10⁻⁸ Pa·m³/s).
Software & Data Management
WAYEAL’s proprietary LeakTest Pro v3.2 software provides full remote control, automated test sequence scripting, and time-stamped data export in CSV and XML formats. Each test record includes operator ID, timestamp, environmental conditions (T, P, RH), raw ion current values, calculated leak rate, and pass/fail status. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures, including role-based access control, immutable log entries, and cryptographic hash validation of exported datasets. Optional integration with LabVantage LIMS or Siemens Opcenter Quality enables seamless traceability from leak test result to batch certificate of conformance.
Applications
- Automotive: Validation of battery module sealing integrity prior to electrolyte filling; coolant loop leak screening for electric powertrain systems.
- Medical Devices: Final sterility barrier verification of implantable housing assemblies (ISO 11607-1), infusion pump manifolds, and diagnostic cartridge casings.
- Aerospace: Pre-flight leak assessment of fuel manifold welds, hydraulic actuator housings, and environmental control system ducting.
- Energy Storage: In-line QC for lithium-ion cell can sealing (dry room-integrated configurations available), and module-level hermeticity certification per UL 1973 and IEC 62619.
- Industrial Vacuum Systems: Commissioning verification of diffusion pump forelines, sputtering chamber gaskets, and electron beam weld joints.
FAQ
What helium concentration is recommended for optimal sensitivity in direct-pressure mode?
A minimum of 5% helium in nitrogen is advised for routine production testing; for ultra-low-leak applications (<1×10⁻⁸ Pa·m³/s), 10–20% helium improves signal-to-noise ratio without compromising safety or cost efficiency.
Can the system be integrated into an automated production line?
Yes—the detector features programmable digital I/O (8 in / 8 out), EtherNet/IP, and RS-485 Modbus RTU ports for PLC synchronization, robotic arm triggering, and PLC-controlled fixture actuation.
Is third-party calibration certification included with purchase?
Each unit ships with a factory calibration report traceable to NIST SRM 2195 (helium permeation standard); optional UKAS or DAkkS-accredited calibration services are available upon request.
Does the instrument support multi-gas analysis beyond helium?
No—this model is optimized exclusively for helium detection (m/z = 4) to maximize sensitivity, stability, and long-term repeatability in industrial leak testing environments.
