Features of creating a reference base in the field of chemical and biological measurements

The paper considers the features of creating a reference base in the field of chemical and biological research. It is noted that there is a high demand for measuring instruments in chemical and biological measurements, at the same time, there is practically no reference base for these measurements. The method of measuring the magnetic susceptibility of substances and the method of dielectrophoresis for determining the polarizability of microparticles are considered in detail. On the basis of the dielectrophoresis method, a primary reference measurement technique (PRMI) was created, which is used to measure the volume polarizability and establish the metrological characteristics of standard samples.
