A helium leak detector, also known as a Mass Spectrometer Leak Detector (MSLD), is used to locate and measure the size of leaks into or out of a system or containing device. The tracer gas, helium, is introduced to a test part that is connected to the leak detector.
Helium Mass Spectrometry Leak Detection Equipment is used to find extremely fine leaks in individual components or larger volumes, the helium gas is used as a tracer gas and its concentration is measured from the leak path.
Fundamentals of Leak Detection In order to achieve an overview of the correlation between the geometric size of the hole and the associated leak rate it is possible to operate on the basis of the following, rough estimate: A circular hole with a diameter D = 1 cm in the wall of a vacuum vessel is closed with a valve. Atmospheric

The turnkey SIMS 1284+ unit, offered by LDA, Inc., measures the helium flow rate escaping from the test package through any and all leaks that are present thanks to a calibrated helium-specific mass spectrometer.
Nov 18, 2010· Leak detection is normally carried out using a helium mass spectrometer leak detector. The mass spectrometer head operates by ionizing the background gas and accelerating the ions through a magnetic field to separate them by mass. A narrow slit is positioned to pass only mass 4 …
In applications where leak rates of components or systems are evaluated against a leak rate requirement, the uncertainty of the measured leak rate must be included in the reported result. However, in the helium mass spectrometer leak detection method, the sensitivity, or resolution, of the instrument is often the only component of
There are many more leak detection methods but none of them is as accurate (localization and quantification) as helium leak detection method. Principle of helium leak detector The Mass Spectrometer Leak Detector is a complete system for localization and measuring of leaks inside or outside of a product.
Sep 18, 2015· The power plant personnel knew that we could perform helium leak detection with a mass spectrometer on condenser systems, condenser tubes, and pressurized systems such as hydrogen cooled generators. The thought then was to use the same process of mass spectrometry leak detection, but on an underground piping system.
A mass spectrometer gas analyzer can be used in tracer gas leak testing to detect helium or hydrogen escaping from a micro-leak. TracerMate CS Leak Test Instrument The CTS Sentinel TracerMate CS instrument is our all-in-one tracer gas leak test system.

HELIUM MASS SPECTROMETER (MS-) LEAK DETECTION . Helium leak detection systems work as follows: He is introduced to a test part that is connected to the leak detector. The helium travels through leak into the leak detector, its partial pressure is senzed respectively measured and results are displayed on istrument as flow rate.
A helium leak detector makes use of a vacuum chamber comprising a sealed, helium- filled container. If Helium leaks out of the container, the mass spectrometer detects the leakage as well as the rate at which the leakage occurs. Design of a helium leak detector
HELIUM LEAK TESTING. Helium Leak Testing is the most sensitive of the common leak testing methods, and covers a wide range of methods that utilize a helium mass spectrometer leak detector such as LACO's TITANTEST™ helium leak detector. These methods can be implemented in simple, manually-operated bench-top systems or in highly automated high volume production systems.
