Helium is one of the smallest gas molecules and because it is inert, helium is safe to use instead of hydrogen and will not react to any parts of the materials that are being tested. A helium mass spectrometer is an instrument we use for the small and extremely difficult leaks. Initially developed during World War II, this instrument uses a vacuum chamber in which a sealed container with helium is placed, helium then leaks out of the container, and then the rate of the leak is detected by a mass spectrometer.
How it works: Helium is used as a tracer gas penetrating small leaks rapidly. By inserting helium in the line, CPL can pinpoint a leak with a sensitivity reading as low as 22 parts per million (PPM). We have filled pipes as large a 60” with helium to locate tiny leaks and have experience great success statewide.Benefit: By using this technique, we are able to find smaller leaks which are extremely difficult to locate. This is also useful when it comes to loud environment. We have found that this technique also worked well with small gas leaks provided that the gas has already been turned off.
Gas Leak Detection
If you are smelling gas and there’s a patch of grass that has turned brown or a tree that looks sick, you may have an underground gas leak. CPL uses flame ionization detector (FID) gas sniffers to detect organic compounds. This method is used over other methods because of its higher concentration and flame ionization sensitivity.
How It Works: Our technicians are fully trained and qualified to operate a flame ionization gas detector to detect where the gas leak is coming from. Upon completing the survey, we will provide you with the location and size of the leak representing the potential hazard and provide you with the necessary information to initiate safety procedures and repairs.
Benefit: The method we use, flame ionization detector, can quickly and accurately detect gas leaks. CPL provides service of doing required gas surveys for mobile homes and other facilities that are to be done on an annual basis.
