描述:Hiden Isochema's MBR is a fully automated system, supplied with an integrated close-coupled mass spectrometer. In co-current flow mode, a gas mixture is applied upstream of the membrane at a controlled pressure and composition, while a dedicated helium flow flushes the downstream side. The gas composition is then analyzed to assess the separation performance of the membrane material. Alternatively, in cross flow mode, the MBR is operated without downstream sweep gas and the performance of the membrane is determined by comparing the downstream and upstream gas compositions. Design features include fully programmable operation, pneumatically actuated shutoff and switching valves with minimised dead volume, a high performance pressure controller and a precision engineered membrane cell with unique integral support structure.
2017年7月份,Hiden Isochema 宣布推出用于氣體滲透膜的專用膜測試反應器-MBR。能夠測試并優化氣體膜分離過程的操作參數和條件。最大程度的滿足氣體膜分離研究和應用領域專業特定的測試需求。是相關科研工作人員提高研究效率和數據可靠性的理想的測試儀器!
采用壓差法與在線質譜DSMS分析相結合的測試原理,將預先處理好的試樣放置在上下測試腔之間、夾緊,對低壓腔以及整個系統進行真空處理;當達到規定的真空度后,向高壓腔充入試驗氣體,并保證在試樣兩側形成一恒定的壓差;氣體在壓差梯度的作用下,由高壓側向低壓側滲透;滲透到低壓腔的試驗氣體,由載氣攜帶至DSMS分析儀,通過實時在線跟蹤各種測試氣體的濃度變化,從而得到分離膜對試驗氣體各組分的滲透量、選擇性、以及滲透速率的定量結果。
