Simultaneous Measurement of two Samples

The Magnetic Suspension Balance can simultaneously measure two different sample materials or sinker (Dual sample version).

The Balance is equipped with unique features, e.g. a self-optimizing Magnetic Suspension Balance controller as well as a failsafe high speed ethernet interface.

Integrated Calculation of Measurement Uncertainty

The software which will be used for controlling RuboSORP Magnetic Suspension Balance contains an integrated calculation of measurement uncertainy according to GUM guidelines (Guide to the expression of uncertainties in measurement). This allows a more holistic view of data and best level of scientific work.

Our Magnetic Suspension Balances are equipped with the latest generation of ultra-modern control electronics. In this way an even better, unrivalled measuring performance is achieved. The newly developed control system contains the specifications listed below:

- High-speed data transfer via Ethernet interface
- Exact approach of the measuring points without signal oscillations
- Online measured data display on the front display
- Failure minimization thanks to latest software application
- Integrated emergency power supply. In the event of a power failure, the Magnetic Suspension
- Balance is automatically set to a safe operating state. Uncontrollable operating states,
- which could lead to the crucible falling off, for example, are thus avoided.

Chlorine Gas Adsorption

The figure shows the experimental results of adsorption measurement using highly toxic chlorine gas. This data was collected simultaneously on two materials within a pressure range of up to 3.5 bar at 10°C. For this purpose, the Magnetic Suspension Balance has been equipped with two sample crucibles to measure both samples at the same time (dual sample measurement).

Adsorption of Biogas on Zeolite

With increasing usage of biogas as energy source, the corresponding purification treatment of its gas components has become increasingly more important. The figure shows the pure gas isotherms of CO2, CH4, N2 and H2 measured on zeolite, which is an industrially used sorbent for biogas purification. In combination with an appropriate dosing unit, the Magnetic Suspension Balance can also be used to measure the corresponding gas mixture adsorption.

Fluid Density Measurement

Sinkers with a known volume can be used instead of sample crucibles for high accurate determination of fluid phase density, even in supercritical atmospheres. The figure shows density data of CO2 measured in sub-critical and supercritical state. By using a sinker and sample crucible as measurement objects a combined measurement of adsorption and fluid density can be obtained.
