The CHRONECT Workstation Glyphosate was
developed for the analysis of glyphosate, glufosinate and AMPA in
complex matrices such as food. Manual steps in sample preparation have
been reduced to only 10 minutes. All other preparation and measurement
steps are done fully automated and nested in about 40 minutes.
By
means of Online SPE-LC-MS/MS glyphosate is concentrated on special
cartridges. In combination with the Sciex Triple Quad 5500 the
determination limit for the difficult matrix black tea is below 3 µg/kg.
For the detection of glyphosate, AMPA and glufosinate an excellent
recovery between 86 % and 96% and a reproducibility of ~ 10% was
measured. This shows that the method is extremely reliable.
The
CHRONECT Workstation Glyphosate consists of a CHRONECT Symbiosis sample
robot with a centrifuge, a vortexer, an agitator and an online SPE unit
with ready-made methods and special CHROSPE glyphosate cartridges. For
simple matrices like C8 or C18, the use of standard SPE cartridges is
also possible. The CHRONECT Workstation Glyphosate is supplied with
ready-made methods for different matrices. The workstation can be
connected to different LC-MS/MS systems. Direct injection, online SPE
with or without sample derivatization are available on the instrument.
