Construction of SORPTEST Device for Testing Resistance of Porous and Non-porous Barrier Materials against Permeation of Volatile Toxic Compounds - part 1

Original language description

The mobile device SORPTEST designated for testing resistivity of porous and non-porous barrier materials used in anti-gas protection against the permeation of volatile toxic compound in static and dynamic conditions has been developed. The rate of permeation in continually observed with the help of high sensitive QCM sensor with a polymeric detection layer. This one is inbuilt in a heated PVDF permeation cell of a new construction. A modular form of SORPTEST device enables a simple change of a character of tested samples (porous, non-porous) and even conditions of measurement. Used software equipment enables observation and evaluation of achieved permeation data in the real time (on-line). Setting and duration of the permeation measurement are automatically displayed and controlled with the help of a computer with original software equipment. After entering tested materials into 3 permeation cells and setting of needed parameters the calibration, resetting and even measurement including processing of permeation data run automatically. Permeation data is immediately available after measurement finishing in the form of the protocol from measurement. As the carrier gases the air (mini pump) or nitrogen (pressure cylinder) are used within measurement in dynamic conditions. This devise has been developed in cooperation with GRYF HB, limited company which is also its producer. Both the permeation cell construction and the permeation device construction are protected as an industrial design. The principle of permeation of gases and vapors by various types of barrier materials, theoretical course of permeation and design of used permeation cells are presented. Individual parts of the SORPTEST device, principle of QCM sensor function, wiring diagram and realization of permeation cells of own construction is described. A method for adjusting the concentration of a test chemical, a method of calibration, and an example of a sorption and desorption curve for a real test chemical within permeation through a porous barrier material are described.
