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 宣布推出用于气体渗透膜的专用膜测试反应器-MBR。能够测试并优化气体膜分离过程的操作参数和条件。最大程度的满足气体膜分离研究和应用领域专业特定的测试需求。是相关科研工作人员提高研究效率和数据可靠性的理想的测试仪器!
采用压差法与在线质谱DSMS分析相结合的测试原理,将预先处理好的试样放置在上下测试腔之间、夹紧,对低压腔以及整个系统进行真空处理;当达到规定的真空度后,向高压腔充入试验气体,并保证在试样两侧形成一恒定的压差;气体在压差梯度的作用下,由高压侧向低压侧渗透;渗透到低压腔的试验气体,由载气携带至DSMS分析仪,通过实时在线跟踪各种测试气体的浓度变化,从而得到分离膜对试验气体各组分的渗透量、选择性、以及渗透速率的定量结果。
