I-Corps: Measuring Parallel Permeation of Gases through Barrier Packaging Materials

该研究小组计划进一步开发一种测量气体混合物通过阻隔材料的渗透率的技术。该团队已经建立了渗透测试设备，利用一种方法将气体渗透测试单元与高真空质谱仪（MS）连接起来。池/MS接口设计减少了测量延迟时间，并能够使用MS检测器实时测量气体渗透。其结果是一个测试系统，可以测量任何气体或气体混合物通过阻隔材料的渗透率。这种单仪器系统可以测量任何气体的渗透，消除了对每种类型的气体进行测试的单独设备的需要。该仪器还可以测量气体和气体混合物的渗透，这是很少有可用的仪器。该技术还可以用一个检测器多路复用多个样品池，从而加快测试吞吐量。该仪器的多功能性和加速测试能力有可能增加单位人员时间和资本投资的测试结果数据。由于包装材料的气体阻隔性能的进步，越来越需要测量超低的气体渗透速率。该技术是一项使能技术，将为用户提供新的和更快速的技术来测试渗透性和创造新材料。

The research team plans to further develop a technology for measuring permeation rates of gas mixtures through barrier materials. The team has built permeation testing equipment that utilizes an approach to interface a gas permeation test cell with a high vacuum mass spectrometer (MS). The cell/MS interface design reduces measurement delay time and enables real-time measurement of gas permeation using a MS detector. The result is a test system that can measure the permeation rate of any gas or gas mixture through barrier materials. This single-instrument system can measure the permeation of any gas, eliminating the need for separate pieces of equipment for each type of gas to be tested. The instrument can also measure permeation of gasses and gas mixtures for which there are few available instruments. The technology also enables multiplexing of many sample cells with one detector, leading to accelerated test throughput.The versatility and accelerated testing capability of this instrument has the potential to produce an increase in test result data per unit of personnel time and capital investment. There is a growing need to measure ultra-low rates of gas permeation due to advances in gas barrier performance of packaging materials. The technology is an enabling technology, which will give users new and more expedited technologies to test permeability and create new materials.
