Vacuum-enabled membrane permeation measurement instrument enables parts-per-million WVTR accuracy

February 18, 2013 // By Julien Happich
VG Scientia's new VacuTran is what the company claims to be a major game-changer for the plastic electronics industry, enabling water vapour transmission rate (WVTR) measurement of barrier layers to better than 10-6 g/m2/day and simultaneous O2 permeation to better than 10-3 cm3/m2/day.

The vacuum-enabled membrane permeation measurement instrument advances detection levels by a factor of 50 to 100 compared with the one-part-in-ten-thousand measurement capability of the current generation of instruments. The advances in time-saving performance and higher sensitivity are significant, with this breakthrough instrument featuring not only a world's first in water vapour transmission rate measurement that exceeds the industry’s specification requirements, but the welcome reduction in results turnaround to days rather than weeks or months. This is of particular relevance to the OLEDs (Organic Light Emitting Displays), OPVs (Organic Photovoltaic devices) and OFT (Organic Fieldeffect Transistor) device markets in the Plastic Electronics industry. 

VG Scienta says that VacuTran's genuine quantum leap in barrier layer permeation measurement has been achieved by combining the company's world-leading expertise in vacuum-based technology to significantly reduce, or eliminate, deleterious background effects, with state-of-the-art mass spectrometry and ultra-clean gas handling along with in-built moisture calibration designed to enable traceability to national standards.
