Traditionally gas concentration has been measured with a gas chromatograph, an invasive test device to analyse gas concentration within double and triple glazed insulating glass units. At the same time, quality control receives more attention than ever before, while the use of gas presses has become more commonplace.
Therefore, insulating glass manufacturers are looking for ways to be being able to verify the proper functioning of the gas press. Unlike with any other scanners, with gas presses, the possible flaws cannot be detected with a naked eye. To that end, Sparklike Oy developed Sparklike Laser™ devices, the only available devices on the market fornon-destructive insulating gas fill analysis for double and triple glazed insulating glass units, even through most coatings and laminated glasses. Sparklike Laser™ devices are based on technology known as TDLAS(Tuneable Diode Laser Absorption Spectroscopy). By using this technology, the device measures oxygen and from there, the amount of argon, krypton or other insulating gas can be calculated.

Sparklike Oy requested ift Rosenheim, a well-known test laboratory to perform a test in order to determine the argon gas concentration in insulating glass units by using a particularly challenging test specimen. This test specimen included samples with different constructions i.e. clear glass, triple glazed units as well as laminated glass with different coatings. The purpose of the test was to verify the results from measurements done with Sparklike Laser Standard™ analyser, by using gas chromatograph as a reference device.
