Fully-automated sample preparation system
Introduction Faster, cheaper, better – main features of the laboratory of the future. To
achieve these objectives, changes in all levels are necessary. One aspect is
the automation of lab processes, but up to now only mostly sub-processes are
automated in the lab.
The presented poster shows the development of a fully-automated sample
preparation system.
details construction with three ABB robots
high throughput of up to 400 samples / day
versatile (different matrices and different methods, e.g. QuEChERS)
processing different methods within the same time
full-automatic: from weighed sample to the prepared HPLC vial no manual
steps are necessary
24 h runtime
