Automated Permeation Breakthrough Analysis Systems

When working with hazardous chemicals, appropriate protective clothing should be worn. These items of protective clothing should be tested to ensure they offer a suitable level of chemical protection. Testing the rate at which a chemical permeates through a material determines the level of protection it can offer. To achieve certification as ‘chemically protective’ by EN ISO 374-1, a glove must accomplish certain breakthrough times against several challenge chemicals.

Ellutia offers a complete system for the automatic analysis of permeation breakthroughs. The system comprises of a number of permeation cells. Optional automated challenge chemical introduction can further increase sample throughput and automation. Once each cell has had the challenge chemical applied on one side of the sample material and automatically samples the headspace from the other side periodically to plot the permeation breakthrough. The Cells can be operated in series or parallel depending on the test requirements. An Ellutia 200 Series GC analyses the Headspace from the cells, and the results are automatically plotted by custom software.
