*1 Although not a common application, gases of substances that are solid at normal temperatures can be generated using gas diffusion tubes. Please contact your licensed GASTEC representative for information regarding specific substances.
*2 This method cannot be applied to substances with extremely high or low vapour pressure or substances with decomposability, corrosiveness, hygroscopicity or polymerizability due to their diffusion rate not being constant.
Suitable for continuous generation of single component gases for calibration over sustained periods of time.
Diffusion tube for multiple components
Solvents such as thinner contain multiple components. Previous models permit the generation of single component gases for calibration purposes. However, a multiple component type diffusion tube enables the simultaneous generation of 4 types of gases for calibration. Employing this tube enhances analytical testing.
