Description

Principles

• Film
  The specimen is clamped between the upper and lower chamber, the upper chamber is purged by a oxygen stream, and the other side of specimen, lower chamber is purged by a stream of nitrogen, due to the effect of oxygen concentration gradient at two sides of the specimen, oxygen molecules will permeate through the specimen into the nitrogen side, penetrated oxygen molecules will be carried to the coulometric sensor which generates the
  proportional signal, so oxygen transmission rate and permeability coefficient will be obtained
  by calculating the sensor signal.

• Package
  The package is mounted on the lower chamber, the outside of the package is air or a pure
  oxygen stream, the inside of the package is purged by a nitrogen stream, oxygen will
  permeate through the wall into the inside of the package, penetrated oxygen molecules will
  be carried to the coulometric sensor which generates the proportional signal, so oxygen
  transmission rate will be obtained by calculating the sensor signal.
