You describe the problem. We clarify the next technical step.Component → objective → suitable specialist
Laboratory or production?
A sensitive laboratory setup may not fit a production cycle.
Stable or sensitive component?
Temperature, deformation, humidity and pressure resistance influence testing.
The inspection principle
Three visibly different measurement principles.
01Pressure decay
02Flow
03Tracer gas / sniffing
Schematic principle, not to scale. The drawings explain the inspection task; performance must be validated on real components.
A practical technical start
Four methods at a glance.
Detection limits and total costs must be evaluated for the actual setup.
- Pressure decay
- Observe pressure change over time; temperature, stabilisation and deformation may affect the result.
- Flow
- Measure gas flow needed to maintain pressure; match range, supply and setup stability to the task.
- Helium
- Detect suitable tracer gas; include gas supply, sealing and equipment requirements.
- Forming gas
- Detect hydrogen-containing tracer gas with suitable instrumentation; consider access, background and the measurement concept.
What happens next
A clear next step for your inspection task.
- 01
Describe the problem
A short description is enough to begin. Add photos or requirements if available.
- 02
Clarify the task
CorDev clarifies open questions with you and identifies the support your task needs.
- 03
Agree the next step
We agree the involvement of suitable specialists with you. Testing or a pilot requires a separate agreement.
Define your inspection task
Which condition rules out a method or requires a practical trial?
Illustrative scenario
Two quotations use different test pressures and sequences. A meaningful comparison first puts the requirements and boundary conditions on the same basis.
This is an illustrative task, not a customer case or a performance promise.Useful information for your enquiry
- The same requirement and limits for every quotation
- Temperature, volume, component behaviour and permitted test medium
- Full cycle, consumables, maintenance and test-system monitoring
The next useful outcome: A traceable selection with outstanding evidence. The linked method selector supports the initial assessment.

Before you ask
Frequently asked questions.
Which method costs least?
Total cost includes the component, cycle, fixture, media, maintenance and incorrect decisions. The method name alone does not determine cost.
Is helium always best?
No. Potential sensitivity is one factor; effort, part behaviour and the actual requirement must fit.
Can we compare on samples?
A shared test plan with representative good and defective parts can support the decision. Scope and reference evidence follow your task.
Does submitting create a paid order?
No. Paid work requires a separate, express agreement.
