Principle
It is a fully automated precision inductivity bridge. Optional attachments like CS-3 and CS-L, enables measurement of temperature variation of bulk susceptibility from -192°C up to 700°C. The measuring coil is designed as a compensated solenoid with an outstanding field homogeneity.
Applications
Temperature dependence of magnetic susceptibility (χ−T) is used to determine changes in mineralogy of natural samples during heat treatment to delineate:
Variation of magnetic susceptibility with temperature from -196°C to 700°C
