Contamination of solid materials, as well as of liquid and gaseous media, is forcing laboratory professionals to face ever more difficult challenges. For example, a basic requirement in the manufacture of pharmaceuticals and chemical agents, for example, is that the product is free of nanoparticles and microstructures. This makes constant monitoring essential.
i3 Membrane provides membranes and filters for the highest standards of particle analysis. Ultra-thin metal finishes made of gold and aluminum are applied to high-quality polymeric membranes to enable optimal reflection properties with the Fourier Transform Infrared (FTIR) microscope, the Raman spectroscope and the Laser Direct Infrared Imaging spectroscope. They also build a suitable conductive substrate for imaging with scanning electron microscopes (EDX/WDX). This makes the standardized membranes ideal for use in asbestos analysis, particle analysis of solid and liquid materials in the pharmaceuticals, chemical and automotive industries, as well as in microplastics analysis and sample preparation (for HPLC and other methods).
For customized fields of application, we produce specially coated track-etched filters made of various polymer compounds of different pore sizes, diameters and coating thicknesses. To stabilize the membranes when in use, the gold- and aluminum-coated filters can be assembled with an aluminum ring.
