Workstation for efficient determination of glyphosate in foodstuff
This workstation by Axel Semrau® has been developed to determine glyphosate, glufosinate and AMPA in complex matrices as for example foodstuff. Manual steps during sample preparation are reduced to 10 minutes only, the entire remaining preparation and measurement is performed fully automated and interlaced in approx. 40 minutes.
Using online SPE-LC-MS/MS glyphosate is concentrated on specific cartridges. Combined with a Sciex Triple Quad 5500 system the determination limit for black tea, a very difficult matrix, is below 3 µg/kg. An excellent recovery between 86 and 96 % and a repeatability of ~ 10 % was measured for the detection of glyphosate, AMPA and glufosinate. This proves that the method is very reliable.
The CHRONECT Workstation Glyphosate consists of a XYZ robot with a centrifuge, vortexer and agitator, an online SPE unit with prepared methods and the specialized cartridges CHROSPE Glyphosate. Utilization of standard SPE cartridges for simple matrices, e.g. C8 or C18 phases, is possible. CHRONECT Workstation Glyphosate will be delivered with ready-for-use methods for different matrices.
Being a front-end solution, the workstation can be coupled to various LC-MS/MS systems. Direct injection, online SPE with or without derivatization of the sample are readily available on the device.
