阻隔膜，作为食品、饮料、药品等的包装材料和电子设备的密封材料被广泛地使用。
特别是最近，在OLED显示屏和电子纸等柔性设备中，对具有高阻隔性能的薄膜的需求日益增加。
但是，高阻隔膜所要求的～10-6g/㎡ /day等级的透过量作为绝对量来测量是非常困难的。
Advance理工通过搭载国立研究开发法人产业技术综合研究所开发的标准电导单元，开发出了高灵敏度测量透过量绝对值的气体透过率测定装置。

特点

使用标准电导单元可以提供绝对校准的测量。
水蒸气透过率为~10 ^-6 g / m² / day，氧气透过率为～10 ^-2 cc / m2 /day。
使用质谱仪，除水蒸气外，还可以测量多种气体物质的渗透性。（O₂、N₂等）

用途

测量以下各种电子器件的密封膜的透气性

有机EL显示器和液晶显示器
电子纸
食品，药品，电子零件等的包装
各种气体气体（O₂、N₂、CO₂、H₂等）防渗透材料

Measurement Principle

Preparation of calibration curve: With no sample placed, flow vapor (or gas) by using Standard Conductance Unit under some amount of vapor (or gas) pressure and measure ion current with a mass spectrometer. Repeat this process several times under the different amounts of vapor (or gas) pressure to make calibration curve.
Sample setting: Set a sample and exhaust a sample chamber with a turbo molecular pump into a high vacuum condition.
Gas introduction and measurement: After reaching the high vacuum condition, introduce vapor (or gas) from the upper side of the sample chamber and start measuring. With the mass spectrometer, measure the ion current of the vapor (or gas) that has transmitted through the sample.
Transmission rate analysis: With the calibration curve, calculate the transmission rate from the ion current of the vapor (or gas) that has transmitted.
