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.
CTS的氮清除泄漏测试消除了影响准确性的因素：
- 解决背景污染的问题，影响测试结果的成本低于硬真空质谱仪测试
- 自动进行测试以获得定量测量并消除操作员主观性和依赖性
- Reduce false failures and gain a more repeatable test process

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.
