Inboard Helium Leak Testing (MSLT)
Inboard leak testing on high-purity gas systems, stainless carrier chemical systems, delivery equipment, filter skids, and HI-VAC systems, for leak rates from 10⁻¹² to 10⁻⁵ mbar·l/s.
Semiconductor · Microelectronics · Fiber Optic
Certified to spec, down to single-digit ppb.
Our inspection and testing services assure that high-purity gas cabinets, panels, filter skids, gas sticks, components, tool systems, laterals, and mains are fabricated and installed to project specifications, and tested to the required leak rate, particle, and impurity criteria.
Certification testing
Outboard Helium Leak Testing (MSLT)
Outboard MSLT on operational facility helium systems to locate leaks in transfer lines, tools, and equipment, eliminating atmospheric contamination, reducing helium loss, and saving operating capital.
Particle Testing
Real-time particle counts on pressurized high-purity gas systems, measured at specified velocities or Reynolds numbers, with channel thresholds of 0.1, 0.2, 0.3, 0.5, 1.0, and 5.0 μm.
Moisture & Oxygen Testing
Real-time trace H2O and O2 testing with QAM's UHP Analytical Test Cart: single-digit ppb to lower ppm, dew points from -110°C to 20°C, with onboard data acquisition and trending.
Impurity Testing
CO, H2, CH4, CO2, and NMHC analysis via RCP and FID analyzers. On-site samples are collected in prepared 1.5L cylinders and analyzed at QAM, single-digit ppb to 5 ppm.
Resources
Management and technicians with the experience for any high-purity scope: proven procedures, equipment resources, data acquisition, and electronic reporting for tool qualification and system commissioning.

Fabrication & installation surveillance
Materials of Construction
Fabricator material receipt, examination, and control processes audited to assure correct materials are issued.
WPS / WOPQ
Auto-GTAW procedures and operator qualifications evaluated to ASME Section IX and project-specific requirements.
Purge & Backing Gas
Gas sources, purifiers, jumpers, and point-of-use filters field-verified to specification, reducing certification testing time.
Welding Surveillance
Weld sample coupons verified per project requirements; UHP procedures, welding, and repairs verified to specification.
PVDF, PP & PFA Welding
Machine and welder qualifications verified to manufacturer requirements; machine parameters verified weld-for-weld during inspection.
Pressure Test Verification
Test gauge, approved media, pressure, duration, criteria, and documentation verified to the project specification.
Inspection, verification & turnover
Weld Inspection (SS, PVDF, PP, PFA)
Production welds inspected by direct visual per the inspection plan and evaluated to the weld acceptance criteria. Plastic welding is verified to the machine weld report.
Installation Verification
Systems inspected for routing, hangers, labels, source, and POC tie-in per drawings, producing a punch list tracked to corrective action and sign-off.
