Lodestone in situ magnetometer system for catalyst characterisation

Lodestone designs and manufactures advanced in situ magnetometer systems based on a patented design developed at the University of Cape Town. The system combines magnetic characterisation with a high-pressure packed-bed reactor, enabling continuous measurement of catalyst evolution under reaction conditions.


Operando capabilities
Equipped with gas flow and GC capabilities, the system enables catalytic measurements while recording magnetic data.

High temperature
Operation up to 800 °C using infrared heating.

High pressure
High-pressure operation up to 50 bar enabled by stainless steel reactor design.

Packed bed reactor
True flow-through reactor geometry for reliable catalytic and kinetic measurements.

Automated control
Fully automated flow, heating and magnetic profiles for ease of operation.
