Scope
This document describes the detection methods for the quality concentration, particle size, dispersion stability, superparamagnetism, magnetic recovery rate, saturated binding capacity of target substances, target capture rate, capture specificity, and capture rate stability of immune magnetic materials. This document is applicable to the performance testing of composite materials with a particle size range of 50 nm to 100 μm, which exhibit superparamagnetism and are surface-fixed with biologically active molecules such as antibodies or antigens.
