TrackPor R

Gold-coated polyester membrane in an aluminum ring

Pharmaceutical fluids and chemical auxiliary agents are subject to strict quality control, just like drinking water and foodstuffs. With the aid of i3 TrackPor R membranes, both organic and inorganic particles in the nano- and micro-range can be analyzed.

Easier handling in everyday laboratory work due to aluminum rings

For easy handling of the i3 TrackPor P membranes in the laboratory, mounting in aluminum rings is indispensable. The particularly smooth, even surface of the i3 TrackPor R polyester membrane is the result of a homogeneous 100/0 nm gold layer. The i3 TrackPor R gold-coated track-etched filters are often used for longer filtration periods; they remain stable even in liquid media. They provide optimal reflection in Fourier transform infrared (FTIR) microscopy and Raman spectroscopy and form a suitable conductive substrate for imaging in scanning electron microscopy (EDX/WDX).

Monitoring of production processes

Contamination during the production process is often due to solid materials such as particles, dust and organisms but can also be due to materials in liquid and gaseous forms such as product residues and aerosols. These must be detected and evaluated. In addition, contamination can be produced by packaging and production equipment. Testing of the end product, often too late, is complex and expensive.

Quantification and qualification of impurities

Another area of use for the i3 TrackPor R is the technical cleanliness testing of functionally relevant automotive parts (particle contamination) in accordance with ISO 16232 and VDA 19. In order to analyze contamination, car parts are sluiced during production. The testing fluid is filtered through the membranes in preparation for examination using light microscopy. In this laboratory environment, too, i3 TrackPor R is an essential tool to aid in achieving precise results.

i3 TrackPor R are individually packaged in mini-petrislides; they have a membrane diameter of 30 mm and are available in three different pore sizes (0.8 µm, 3 µm and 5 µm). One container contains 50 items.
