Original Equipment-Grade Technical Support! Professional Repair Service for Linxon Helium Mass Spectrometer Leak Detectors, Empowering Precise Industrial Detection

As a cost-effective leak detection equipment brand under INFICON, Linxon helium mass spectrometer leak detectors (focusing on the LX218 series) are widely recognized in semiconductor manufacturing, automotive, refrigeration and air conditioning, aerospace, and other industries. With support for three leak detection modes—vacuum mode, spray mode, and sniffer mode—along with advantages such as fast startup (<3 minutes), high pumping speed, and low helium background interference, these detectors have become **core testing equipment** in various industrial fields. The LX218 series includes three main models: LX218 WET (portable wet-type), LX218 DRY (portable dry-type), and LX218 MODULE (modular-type), all of which are active products with no discontinued models. However, long-term high-load operation under harsh industrial conditions can easily lead to faults such as sensitivity degradation, abnormal background values, and startup failures. Unprofessional repairs may cause irreversible damage to equipment performance. To address these pain points for enterprises, the company officially launches exclusive **professional repair services** for Linxon helium mass spectrometer leak detectors, safeguarding production continuity with targeted technical solutions and full-process guarantees.

Core Service Advantages: Precise Adaptation, Professional Repair

1. Full Model Coverage + Targeted Fault Resolution

Specializing in the core LX218 series models, we have developed standardized solutions for high-frequency faults: accurately addressing issues such as soaring helium background values, automatic calibration failure ("Sensitivity Low" alarm), turbomolecular pump startup failures, and slow response in sniffer mode. We deeply resolve core problems including ion source contamination, standard leak blockage, solenoid valve seal aging, and **vacuum system leakage**, fully adapting to the technical characteristics of the series’ three detection modes and modular design.

2. Original Equipment-Grade Process Guarantee, Factory-Level Performance Restoration

Based on in-depth analysis of Linxon’s core architecture, we adopt INFICON original-specification accessories and repair processes: chemical cleaning or replacement of ion sources (integrated with INFICON mass spectrometry components), turbomolecular pump overhaul (bearing and lubricating oil pack replacement), standard leak calibration and gas refilling, and sealing optimization of vacuum systems. For LX218 DRY’s oil-free dry diaphragm pump and LX218 WET’s oil-sealed rotary vane pump, we implement model-specific maintenance protocols to ensure that after repair, the equipment’s minimum detectable leak rate (5×10⁻¹¹ mbar·l/s in vacuum mode, 1×10⁻⁸ mbar·l/s in sniffer mode), pumping speed, and response time meet factory parameters.

3. Full-Lifecycle Services Covering Multi-Scenario Needs

In addition to fault repair, we provide customized preventive maintenance (in accordance with original factory standards: ion source maintenance every 6-12 months, mechanical pump oil and filter replacement every 3-6 months, annual seal replacement). For equipment relocation requirements, we offer specialized services including shockproof packaging, vacuum locking, and post-installation full-range calibration, avoiding modular component displacement during transportation—critical for the LX218 MODULE’s integrated system applications.

4. Efficient Response Mechanism, Reduced Downtime Losses

We support 24-hour emergency response, offering flexible service modes: on-site repair for production line supporting equipment and mail-in repair for portable models. A detailed inspection report is issued within 24 hours of receiving the equipment. We maintain in-stock inventory of core Linxon LX218 accessories (e.g., helium spray guns, sniffer probes, and seals) to significantly shorten repair cycles. Additionally, we provide the "Linxon Leak Detector Common Fault Quick Reference Manual" for free, helping enterprises quickly troubleshoot simple issues.

Successful Case: 32-Hour Recovery of High-Voltage Equipment Detection After LX218 DRY Fault Repair for a Power Equipment Factory

Customer Background

A power transmission equipment manufacturing enterprise relied on the Linxon LX218 DRY (portable dry-type) helium mass spectrometer leak detector for critical component factory inspection—specifically for sealing testing of high-voltage switches. The equipment suddenly malfunctioned: the helium background value soared to 3.8×10⁻⁷ mbar·l/s, the turbomolecular pump shut down frequently after startup, and the screen displayed "TMP Fault". This forced a complete halt to the high-voltage switch detection line, resulting in potential losses exceeding 35,000 yuan per hour and risking delays in order delivery. As the LX218 DRY is the preferred model for clean environments (such as the enterprise’s precision manufacturing workshop) due to its oil-free operation and high reliability, the fault posed an urgent production crisis.

Fault Diagnosis & Repair Process

Emergency Support: Specialized engineers were dispatched to the site within 2.5 hours of receiving the report. Combining the LX218 DRY’s dry diaphragm pump characteristics and the customer’s industrial working conditions, diagnostic tools identified the root causes: worn turbomolecular pump bearings leading to substandard rotational speed, ion source contamination from long-term testing of industrial components, and insufficient vacuum due to degraded mechanical pump oil.

In-Depth Repair: The equipment was transferred to a cleanroom repair workshop. The turbomolecular pump underwent full disassembly and overhaul, with original-specification bearings and lubricating oil packs replaced. The mass spectrometry chamber and ion source were disassembled and cleaned, and the integrated INFICON mass spectrometry component was recalibrated. Degraded mechanical pump oil and filters were replaced, and the DN 25 ISO-KF connection flange interface was resealed to enhance vacuum tightness.

Precise Calibration: After repair, full-range calibration was performed using a standard leak hole (1×10⁻¹⁰ mbar·l/s). Parameters for both vacuum and sniffer modes were optimized to simulate high-voltage equipment detection scenarios, ensuring compliance with ISO and MIL-STD standards—consistent with the LX218 series’ certification requirements.

Repair Results

• The equipment fault was completely eliminated: the helium background value stabilized below 6.5×10⁻⁹ mbar·l/s, the turbomolecular pump operated stably without shutdowns, and detection accuracy was restored to factory levels.
• From fault reporting to detection line resumption, only 32 hours elapsed, reducing the enterprise’s potential losses by over 1.12 million yuan and ensuring on-time order delivery.
• A customized maintenance plan (quarterly inspections + annual in-depth maintenance) was formulated for the customer. The equipment has operated continuously for 11 months without faults, and the consistency of detection data has improved by 35%—meeting the enterprise’s high-precision testing requirements for power equipment.
