[Analysis Case] TDS Analysis of Glass Samples
It is possible to analyze desorbed gases by temperature increase even with transparent samples that allow infrared rays to pass through.
The temperature-programmed desorption gas analysis method (TDS) is a mass spectrometry technique that directly heats a sample by irradiating it with infrared light and monitors the gases generated at each temperature. When analyzing samples that cannot absorb infrared light, such as glass substrates, it is possible to conduct the analysis by changing the sample stage from transparent to black. The black stage absorbs infrared light, raising its temperature, which in turn increases the temperature of the sample through thermal conduction, generating gases.
