Linseis – Thermal Analysis

High Pressure STA and MSB

The ability to measure Heat Flow and Mass loss/gain at high temperatures and pressure is a specialist technique which is gaining interest to have samples tested to have dual sets of data at exactly the same conditions.  Linseis offer the High Pressure STA to meet the needs of research in conditions outside of ambient pressure.  There various configurations possible to cover temperatures from ambient to 1000oC, -170 to 1800oC.  Naturally the selection shall require some discussion and our specialist knowledge built up over years shall be important in our guiding your research interests.  Scientex and Linseis shall be pleased to discuss any project which would benefit from STA where pressure is a key factor in analysis.

Sorption studies at high pressures and elevated temperatures are often associated with corrosive atmospheres.  The principle of the Magnetic Suspension Balance (MSB) has come out of Patent and Linseis has been very active in this technology sector for a number of years.  Linseis offers a great alternative to its competitor.

With the MSB, gravimetric measurements in a wide temperature and pressure range and under aggressive media can be done. An MSB consists of a micro balance for recording the measurement values, a suspension coupling which carries the weight of the sample, a sensor for the position measurement of the levitation part and a control unit to control the suspension coupling.

The contact-less transmission of the sample weight is realized with a levitation magnet and a holding magnet. The levitation magnet consists of a permanent magnet and the holding magnet consists of an electromagnet hanging on the balance. The position sensor delivers the actual position of the levitation magnet and the PID controller makes a stable levitation position with the electromagnetic force as the actuating variable. Through the magnetic coupling a micro balance can be set up at environmental condition. Therefore the balance is protected from high temperatures, pressure and aggressive media.
