Automated Permeation Analysis Systems for EN 374
Mar 21 2023
When handling dangerous chemicals, it is essential to wear protective clothing that has been tested to ensure it provides sufficient chemical protection. The level of protection is determined by testing the rate at which chemicals permeate through the material. For gloves to receive certification as ‘chemically protective’ by EN ISO 374-1, they must meet specific breakthrough times against several challenge chemicals.
Ellutia has developed an automated system for analysing permeation breakthrough rates. The system includes up to 18 permeation cells and optional automated challenge chemical introduction to increase sample throughput and automation. The cells hold the challenge chemical to one side of the sample material and periodically sample the headspace from the other side to plot the permeation breakthrough. The cells can be operated in series or parallel depending on the test requirements. The Ellutia 200 Series GC then analyses the headspace from the cells, and custom software automatically plots the results in real-time.
