Argon content in air could be detected in an indirect way – by measurement of oxy- gen content in air. If the oxygen content is reduced and the only additional gas present in the installation was argon then an electrochemical oxygen sensor can be utilized.
What is the test for argon?
New specifications prepared at the 53rd JECFA (1999) and published in FNP 52 Add 7 (1999).

Flame test The flame of a burning splinter of wood is extinguished when inserted into an upright test tube filled with argon
How do you test for an argon gas leak?
The heart of the most sensitive and accurate instrument for detecting extremely small leaks is the mass spectrometer, which is used to measure the rate of flow of a tracer gas through leaks using vacuum, pressure or vacuum-pressure techniques.
Is argon hard to find?
Though inert, argon is far from rare; it makes up 0.94 percent of Earth's atmosphere, according to the Royal Society of Chemistry (RSC).Feb 20, 2015
What is the proper method of testing for gas leaks?
The most commonly used leak test methods are underwater bubble test, bubble soap paint, pressure and vacuum decay, and tracer gas detectors (halogen, helium and hydrogen).
How do you perform a leak test?
The leak test is performed by immersing a part, usually a sandwich composite structure, in a hot water tank. The temperature of the water induces the expansion of air in the structure, and if a crack or a delamination is present, gas bubbles escape the structure and are immediately detected by visual inspection.
How do I know where the gas smell is coming from?
Roaring or Hissing Sound Usually, the source of the leak is the natural gas connection at the back of an appliance, in which case you'll most likely be able to smell the gas leaking indoors.
Is there an app to detect gas leaks?
