Reliable Laboratory Filtration for Analytical Testing Using Membrane Filters
Sound analytical testing starts prior to a sample coming into contact with an instrument. The quality of the end result can be affected by the sample collection, storage, preparation and filtration. Unwanted particulate matter, suspended solids, aggregates or microorganisms may interfere with sample handling even when the analytical method and instrument is controlled properly and in some workflows, interfere with instrument performance. Membrane Filters provide a controlled means of removing particulate material from liquid samples. Membrane filtration may be applied for sample clarification, analytical sample preparation, microbial retention and protection of sensitive analytical systems, depending on membrane chemistry, pore characteristics and device format. However, filtration is only one part of the analytical process; selecting a suitable membrane and controlling the filtration procedure are essential to improve sample quality without compromising analyte recovery.
