Leaks are not always visible, but their consequences—loss of efficiency, product damage, field failures, and customer rejects—are.
In today’s increasingly demanding industrial environment, precise leak detection is not optional—it’s a necessity.
What Is a Tracer Gas and Why Is It Used?
Helium, known as a tracer gas, is an inert, safe, and non-toxic substance introduced into closed systems to identify even the smallest leaks invisible to the naked eye.
Why Helium is ideal for Leak Detection
- Extremely light: As the second-lightest element in the universe, its atomic size allows detection of micro-leaks smaller than a bacterium.
- Safe and non-reactive: Non-flammable and non-corrosive, safe for vacuum and pressure systems.
- High mobility in closed systems: Its rapid diffusion allows precise detection in less than 0.5 seconds.
Pros of Using Trace Gas for Leak Detection
Extremely small molecular size:
The best ally for detecting micro-leaks in sealed systems where other methods cannot reach that sensitivity.
High sensitivity:
Very low atmospheric presence (~5 ppm) allows interference-free detection.
Compatibility with advanced technology:
Works seamlessly with mass spectrometers capable of detecting leaks as small as 1×10⁻⁹–10⁻¹⁰ mbar·L/s.
Non-reactive with materials:
As a noble gas, it is safe for delicate components and controlled environments.
Immediate results:
Its high diffusion rate speeds up testing processes in production and laboratories.
Tracer gas is not only ideal but also the most reliable method for leak-tightness testing in sectors such as automotive, HVAC, refrigeration, medical devices, aerospace, and e-mobility, where a leak can compromise safety, efficiency, or regulatory compliance.
