New technology for automated sample preparation of solids

Sample in – answer out, it should be that simple.

This is possible for some analytical methods like routine titration, but not yet for seperating analytical methods like HPLC.

Sample preparation is still the biggest bottleneck and is also considered as one of the biggest challenges. A laboratory technician spends more than 60% of the time on sample preparation and documentation.

This is only due to the fact that a huge part of the sample preparation is done manually. Imagine the potential time savings when sample preparation is automated.

Apart from improved efficiency, there are other at least equally important aspects that highlight the importance of automated sample preparation. These are the increasing demands for traceability and thus for documentation. In addition, unavoidable human errors can be excluded.

The current situation with Covid-19 shows that further automation is certainly the right strategy.

The good news is, there are several automation solutions for laboratories available.

Liquid handling or pipetting robots are widely used and accepted today because the advantages are well known.

Why have none of the currently available technologies and systems been established?

There are various reasons:

  • The gain in efficiency is small, as samples are processed sequentially

  • Cleaning between samples consumes large amounts of solvent and requires additional time

  • Automated cleaning of different modules is challenging and the likelihood of carry-over and cross-contamination is high.

The lack of simple standard solutions has led to the development of various machines specially designed for individual applications. Such systems are only sustainable if a large quantity of identical or similar samples is available.

Otherwise the costs of such an investment are in no relation to the benefits.

accroma labtec has taken up the challenge and with its new technology is introducing a simple standard sample preparation robot to the market. The specially developed sample preparation vessels allow parallel working - several samples can be processed at the same time. Each of the samples to be prepared could even have different preparation Methods. A user has nearly unlimited possibilities to combine the different steps: Weighing, Shaking (milling, extracting, mixing), Dispensing, Pipetting, Filter, HPLC analysis, Centrifugation.

With accroTubes, there is no need to clean the mill or the extraction vessel. As a result, carry-over and cross-contamination are avoided and an enormous time saving is achieved.

Various applications have already shown that the utilization of HPLC or UHPLC instruments can be increased. Results are available on the same day, as samples are prepared in parallel to the analysis.

Focus on the important
Highly qualified employees no longer have to spent most of their time for routine work. They can focus on more value added tasks. 

Increase efficiency and capacity 
Working hours are no longer a limiting factor. Automation helps to increase the productive time of your instruments.

Improve traceability 
Automated sample preparation automatically leads to more detailed and accurate documentation that proves the correctness of the results.
