Automated sample preparation and analysis

Precise, reproducible and tireless

Automated sample preparation with robot-based systems. System image

With our robot-based sample preparation and analysis systems, we free the laboratory from routine analyses and relieve employees from constantly repetitive tasks.

Robot-based systems allow sample preparation to be carried out more reliably and remain open to future changes. This is because changing requirements for analysis will also require changes to sample preparation processes in the future.

Optimization through automation

Constantly increasing quality demands on raw materials and end products in the industry require modern preparation technologies, the precision and optimization of production processes and the monitoring of product quality.

The machines and systems we have developed support our customers in increasing their productivity and analytical reliability by providing them with processed samples and even analytical results quickly and reliably.

SIEBTECHNIK TEMA offers you a wide variety of machines and systems for automation. These diverse components are available individually or you can use us as a system provider in the field of sampling and sample preparation.

Operating behavior & mechanical features

The process in the AMAS begins with the filling of the drying tray with the moist bulk sample, which is then evenly distributed in the tray and weighed.

After a set drying time, the tray is removed from the oven, weighed and returned to the oven.

This last step is repeated until the material has dried and two consecutive weighings show constant weight. After emptying and cleaning the tray, it can be refilled.

If the AMAS is supplemented with an eccentric vibrating mill for ultra-fine comminution, the sample material is then prepared ready for analysis.

Operating behavior & mechanical features

In the first step, the material to be analyzed is fed into a screening machine, which fractionates it into the various grain sizes. For this purpose, the sieving machine is equipped with a sieve tower. After fractionation, the sieves are removed individually by a handling device, weighed and emptied. The quantity of material required for the Solid Testing Drums is compiled proportionally from the required fractions and fed to the test drum, which is swiveled into the filling position.

Once the trommel process is complete, the Solid Testing Drums are swiveled into the emptying position and emptied while the trommel is rotating. The tumbled material is then fed back into the screening machine. After fractionation, the screens are removed from the handling device, weighed and emptied.

The emptied screens are temporarily stored in a magazine and stacked back onto the screening machine and automatically fixed in place once the base has been emptied.

 

The SIEBTECHNIK TEMA automatic grinding and pressing system combines all processes from pre-grinding of fist-sized sample materials, dividing, ultra-fine grinding and pressing of the powder into a tablet in one device.

Automatic milling and pressing system (AMP)

The fully automatic grinding and pressing system can be used to convert bulk material samples into test specimens for an XRF or XRD analyzer.

Testing of sampling and sample preparation systems

Testing a sampling system for systematic errors is very time-consuming and labor-intensive and is usually carried out on the basis of comparative sampling. This involves comparing the samples obtained by the automatic system with those obtained by a reference method – manual sampling from a stationary belt.

Thanks to the experience of our long-serving employees, our automatic sampling systems are designed and constructed in such a way that they reliably produce a representative analysis sample. This is because all the individual devices used are always selected and designed with the necessary care and technical knowledge.
