Leak testing of pipe joints, tubes and fittings in heating and refrigeration components such as coils and compressors during assembly manufacturing is critical. With the permissible leak rate as low as 0.5 grams of refrigerant loss per year, conventional sniffer testing is not a reliable method to detect such small leaks. Sniffer tests sample the background to detect helium escaping from a leak. However, background helium concentration fluctuations can make it difficult to consistently distinguish good from bad product and can result in false leak failures.

What Is the Nitrogen Leak Testing Procedure?
The CTS nitrogen purge solution is a tracer gas leak test system that combines theTracerMate II控制测试并提供结果的仪器，质谱仪和CTS净化盖壳，将其夹在测试的关节上。
The CTS nitrogen purge clamshell device (image, right) has inner and outer chambers that surround the part test area. The chambers have ports that allow nitrogen to enter the cavity and force out ambient atmosphere.
在泄漏测试周期中由TracerMate II, the clamshell inner chamber collects the tracer gas leaking from the part. The outer chamber then provides a constant low positive pressure nitrogen curtain to hold back and prevent ambient background from entering, effectively isolating the inner chamber.
The gas from the chamber is drawn into the mass spectrometer, which analyzes the gas mixture to measure the amount of tracer gas. The mass spectrometer communicates results to the TracerMate II, and these readings are then displayed as the instrument determines and signals a “pass” or “fail” (green lights or red lights) for the nitrogen leak test.
Our handheld nitrogen purge clam shell devices are small, custom designed to your application, and easily maneuvered to clamp over components, fittings, and joints. The nitrogen purge custom benchtop test fixtures are designed to fit a broad range of applications.

Nitrogen purge leak testing is an effective method of detecting micro-leaks in pipe joints, tubing, and small parts. Industries ranging from HVAC/R to medical choose tracer gas systems because they are more reliable than other tests, many of which are easily affected by environmental factors.
- Compatible with multiple gases, including helium, forming gas, and refrigerants
- 检测到低至10-6 SCC/S的泄漏
- Increased sensitivity for improved leak detection accuracy: reduces background to 10-7 atm-cc/s range
- Versatility for use in a broad range of heating and cooling applications
