This solution not only realises what QuEChERS stands for (Quick, Easy, Cheap, Effective, Rugged and Safe), it also reaches a high matrix reduction for minimized ion suppression and purer extracts for better results.
In many laboratories
the processing of complex matrices is performed without the use of QuEChERS,
because these often require additional manual working procedures that are very
time consuming. Many fatty matrices, for example, require freezing out of the sample,
which is a considerable burden.
After LCTech has
developed an automated QuEChERS method for dried matrices such as tea or spices
and standard matrices such as fruit or vegetables, which are already
established in laboratories, they now also cover fatty matrices such as butter
or avocado. This non-dispersive method is quick and easy to implement at a
reasonable price.
Small, efficient and
ready-to-use SPE columns, which contain a LCTech proprietary sorbent with high
matrix retention, allow minimised ion suppression with high recoveries and low
standard deviations. In addition, less solvent is required, the extracts are
cleaner and the results are improved versus using the conventional method. This
makes the final analysis more robust, the data is easier to interpret and
downtimes are avoided as no matrix contamination occurs.
‘The non-dispersive process of the method in combination with the miniaturized SPE columns allows a clean-up within approx. 10 minutes’
For the automated application of the LCTech QuEChERS
method, the FREESTYLE robotic system is equipped with a SPE module. The
non-dispersive process of the method in combination with the miniaturized SPE
columns allows a clean-up within approx. 10 minutes.
To increase the degree of automation, the robotic
system can be connected to a LC-MS/MS via a HPLC direct injection module.
Directly after SPE clean-up, an aliquot is injected for analysis while the next
sample is prepared. Thus, clean-up and measurement of up to 120 samples in a
sequence can be coupled and lead to an optimal utilisation of the LC-MS/MS
system.
FREESTYLE has just a few moving or electrical parts to
minimise service needs and downtime. The system can be flexibly combined and
set-up with other modules for additional applications. This leaves the freedom
to adapt it to the changing requirements of everyday laboratory work.

technology of FREESTYLE QuEChERS for yourself, you can visit the LC Tech booth
