WAYEAL SFJ-16M Modular Helium Mass Spectrometer Leak Detector

Overview

The WAYEAL SFJ-16M Modular Helium Mass Spectrometer Leak Detector is an engineered solution for high-sensitivity, production-grade vacuum integrity verification. Based on quadrupole mass spectrometry operating in the 2–4 atomic mass unit (amu) range, it detects helium tracer gas with exceptional selectivity and signal-to-noise ratio. Unlike conventional pressure decay or bubble test methods, the SFJ-16M employs residual gas analysis principles—ionizing ambient helium atoms, separating ions by mass-to-charge ratio via a radiofrequency quadrupole filter, and quantifying ion current at the Faraday cup detector. Its dual-mode vacuum architecture supports both ultra-high sensitivity (ULTRA) and rapid throughput (FINE) operation, enabling seamless adaptation to diverse leak testing workflows—from semiconductor chamber qualification to lithium-ion battery cell sealing validation.

Key Features

• Modular mechanical design: Independent vacuum interface, analyzer head, and control electronics allow flexible integration into automated test cells, conveyor-based inspection lines, or cleanroom-compatible stations.
• Dual ion source configuration: Two iridium-coated yttria filaments provide redundancy and extended service life; automatic switching ensures uninterrupted operation during filament aging or thermal cycling.
• Multi-range sensitivity modes: ULTRA mode delivers 5.0×10⁻¹³ Pa·m³/s minimum detectable leak rate (MDLR) at >5 L/s helium pumping speed; FINE mode achieves 1.0×10⁻¹² Pa·m³/s with optimized response time for high-volume screening.
• Sniffer probe compatibility: Integrated support for handheld helium sniffing with MDLR down to 5.0×10⁻⁹ Pa·m³/s—ideal for localized leak localization in assembled systems where vacuum chamber access is impractical.
• Real-time multimodal display: 5-inch color TFT touchscreen renders numeric leak rate, dynamic bar graphs, and time-resolved trend curves—enabling immediate pass/fail assessment without external software.
• Industrial-grade I/O architecture: Native RS-232/RS-485 serial communication and Ethernet (LAN) interface facilitate PLC synchronization, SCADA integration, and MES data handshaking per ISA-95 Level 2 protocols.

Sample Compatibility & Compliance

The SFJ-16M accommodates a broad spectrum of vacuum-compatible components across regulated and high-reliability sectors. Its DN16 KF and DN25 KF vacuum ports conform to ISO-KF standard flange dimensions, ensuring mechanical interoperability with common roughing and high-vacuum pumping systems—including optional integrated turbomolecular or dry scroll backing pumps. The instrument operates within ambient temperature ranges of 0–40 °C and meets electromagnetic compatibility requirements per EN 61326-1. While not certified as Class I, Division 1 equipment, its DC24V power architecture enables safe deployment in non-hazardous industrial zones. For quality-critical environments—including ISO 13485-certified medical device manufacturing and IATF 16949-compliant automotive EV battery lines—the SFJ-16M supports audit-ready data logging with timestamped event records, user-access controls, and configurable retention policies aligned with FDA 21 CFR Part 11 electronic record guidelines.

Software & Data Management

The embedded firmware provides deterministic real-time acquisition with sub-second response latency and <95 s cold-start vacuum stabilization. All measurement metadata—including test ID, operator code, timestamp, pressure trace, and pass/fail status—is stored locally in non-volatile memory and exportable via USB or network transfer in CSV format. Optional PC-based software (WAYEAL LeakView™) extends functionality with statistical process control (SPC) charting, multi-channel comparative analysis, and automated report generation compliant with ISO/IEC 17025 documentation templates. Remote diagnostics and firmware updates are supported over secure TLS-enabled HTTP endpoints, minimizing downtime during preventive maintenance cycles.

Applications

The SFJ-16M serves as a core metrology asset in industries where hermeticity directly impacts safety, performance, or regulatory compliance. In photovoltaic module manufacturing, it verifies edge seal integrity of laminated glass-EVA-backsheet assemblies prior to field deployment. Within semiconductor front-end fabrication, it validates gate valve actuation integrity and vacuum chamber weld quality under ISO Class 5 cleanroom conditions. For electric vehicle battery pack producers, the system performs 100% inline leak testing of aluminum die-cast enclosures using helium pressurization (up to 1800 Pa gauge). Additional validated use cases include MRI cryostat housing certification, HVAC heat exchanger brazing verification, and implantable pacemaker canister seal validation per ISO 11607-2 accelerated aging protocols.

FAQ

What vacuum pumping configurations are supported?
The SFJ-16M operates natively in vacuum mode and accepts externally pumped systems. Optional integrated turbomolecular or dry scroll backing pumps are available as factory-configured bundles (e.g., SFJ-16M+).
Does the instrument support helium recycling or recovery?
No built-in helium recovery is provided; however, the low helium consumption (<10 mL/min typical in sniffer mode) and modular gas inlet design enable third-party recirculation loop integration.
Can the SFJ-16M be calibrated in-house?
Yes—NIST-traceable calibration kits (including certified micro-leak standards from 1×10⁻¹⁰ to 1×10⁻⁷ Pa·m³/s) are available; full calibration procedures are documented in the user manual per ISO/IEC 17025 Clause 6.5.
Is remote monitoring possible without proprietary software?
Yes—standard Modbus TCP and ASCII command sets over Ethernet allow integration with custom HMI platforms or enterprise MES systems without vendor lock-in.
What is the expected mean time between failures (MTBF) for the ion source?
Under continuous operation at ≤200 Pa background pressure, dual iridium-yttria filaments achieve ≥8,000 hours MTBF per filament, with automatic switchover preserving uptime.
