The Series 8900 Acrylonitrile Analyzer provides direct measurement of Acrylonitrile in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits.The Series 8900 Acrylonitrile Analyzer employs a flame ionization detector (FID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons.

The Ambient Oxygen Ingress Rate (AOIR) method, can measure the permeability of oxygen through films in finished packaging. The rate at which oxygen passes through a packaging film is a key factor for food products packaged under a modified atmosphere designed to exclude oxygen and inhibit the growth of microorganisms, thereby prolonging the shelf life of the product. Most existing techniques measure oxygen permeability of film before it has been incorporated into the package – where the process of heating, stretching and forming can affect the film’s properties.

The need for measuring the throughput of water vapour through packaging films or barriers has numerous drivers. The obvious one of typical food packaging is now well served by readily available permeation measuring instruments. The more demanding requirement for films used for the present commercial generation photo voltaic solar cells is arguably within the limit of present day commercial instruments. However the need for extreme hermeticity to water vapour in the construction of organic LED displays has set the latest challenge to the instrument manufacturers.

The Hot Tack Tester is a highly sophisticated instrument for testing sealing properties of packaging material. It is being used in research and development as well as in SQC/SPC applications for raw materials; semi finished goods and finished packaging products. The Hot Tack Tester permits evaluation of sealability and hot tack under a broad range of testing conditions to optimize packaging machine settings and to ensure consistent quality of the product. The instrument is also a practicable and helpful tool to packaging material manufacturers and end-users for incoming material inspection and for obtaining optimal production line speed.

Nearly all the above mentioned characteristics are affected by the water content. Upon injection-moulding, the pellets used for the production of polyamides are extremely dry. The moisture content of the material increases due to the warm and damp climate prevailing inside the Polyamide Conditioning Chamber, hence the optimum of characteristics is achieved.

Shore hardness is a measure of the resistance of a material to penetration of a spring loaded needle-like indenter. Hardness of Polymers (rubbers, plastics) is usually measured by Shore scales. Shore A scale is used for testing soft Elastomers (rubbers) and other soft polymers. Hardness of hard elastomers and most other polymer materials (Thermoplastics, Thermosets) is measured by Shore D scale. Shore hardness is tested with an instrument called Durometer. Durometer utilizes an indenter loaded by a calibrated spring.

For determining static and dynamic friction coefficients to ISO 8295, ASTM D 1894, ASTM D 2534 and TAPPI T549. To measure the friction behavior between two films a film sheet is laid over the glass plate of the table and fastened in place. A second film sheet is fastened round the sled. During the test the force required to pull the sled is measured.

The miniaturized specimen are used according to the corresponding conditions present, if it is not possible to use the preferred specimen. This can be the case, e.g. if specimen must be taken from finished components or semi-finished products. These specimen are, however, not suitable for determination of comparable single-point data, since they lead to different test results.

The modulus of elasticity describes the stiffness of a plastic. This value is very dependent on various factors such as, loading speed, temperature and specimen history. It corresponds to the slope of a stress-strain curve. Since this slope is not linear for many plastics, the result of this value depends on at which strain it is taken.

Impact Resistance is the resistance of a plastic to fracture by shock loading. The ability of a plastic film to withstand an impact load depends on its toughness. There are different impact testing techniques that are used to determine the impact resistance of plastic materials. In general, they can be broken into two categories, ……
