Description: Get to know our new measurement technology and and solutions for our customers!
SEMPA LAB is constantly striving for new inventions and solutions for our customers. Our R&D activities and JDP’s (Joint Development Programs) with renowned national and international cooperation partners are also looking into advanced measurement technologies which are required for nowadays high end manufacturing processes. The main focus has been on transfer rates of permeates through barrier materials and certain sensing technology.
HiBarSens® stands for ultra reliable measurement of permeation properties of barrier films. It is used for quality control of barrier film production processes as well as in research and development. Due to its flexibility and yet simplicity, HiBarSens® is your perfect choice to determine sample and application specific barrier properties such as the water vapor transmission rate (WVTR) or the water vapor breakthrough behavior (Lag time) under very different measurement conditions. HiBarSens® is the first s
HiBarSens® features three measurement modes. Any of them fulfil the mandatory steady-state measurement condition. In addition to the conventional Carrier Gas Mode , which uses a carrier gas flow through the permeation cell, high performance modes can be easily applied, especially for ultra-high barrier films (<<10-4 g m-2 d-1). In Diffusion Mode , permeate transport is driven by diffusion only. In Combination Mode , a permeate accumulation phase alternates with a carrier gas phase.
