«» () 10 50 , , - . . - . : , , , , , , . A complex analysis of ultrafiltrational "Trumem" metal-ceramic membranes (MCM) with pore diameters 10 nm and 50 nm was carried out. The structure parameters, physicochemical and basic operating characteristics of these membrane were investigated. The MCM's position among the modern ultrafiltrational membranes was established. The express method of ultrafiltrational MCM analysis with protein-mixture calibration was developed. Key words: membrane, ultrafiltration, structure, pore size, properties, calibration method, proteins.
