Video i3TrackPor track-etched gold-coated membrane Particles can arise during the production of pharmaceutical liquids. These can pose a significant health risk. Immune reactions and capillary occlusions are an example. Learn more about the particle analysis in the video. i3 Membrane has developed special membranes for applications in the pharmaceutical industries. The track-etched filters, which are coated with gold by vapor deposition, deliver optimal reflection in Fourier transform infrared (FTIR) microscopy and Raman spectroscopy. They make a suitable conductive substrate for imaging with scanning electron microscopy (EDX/WDX). The different pore sizes of the polyester membranes allow the filtration of all organic and inorganic particles. The filters are an indispensable tool for many companies in the pharmaceutical industry, the chemical industry and the automobile industry.
