The AutoMate-Q40 is a revolutionary system specifically designed and optimized to automate the QuEChERS sample preparation workflow.
The system is configured ‘out of the box’ to conduct two of the most popular QuEChERS sample preparation methods: AOAC 2007.01(Pesticide Residues in Food by Acetonitrile Extraction and Partitioning with Magnesium Sulfate) and EN 15662.2008 (Foods of Plant Origin—Determination of Pesticide Residues Using GC-MS and/or LC-MS/MS Following Acetonitrile Extraction/Partitioning and Clean-up by Dispersive SPE—QuEChERS method).
The AutoMate-Q40 system automates the following sample prep functions:
Opening/closing sample vials
Addition of solid reagents (ex. salts, buffers)
Identifying liquid levels
The AutoMate-Q40 incorporates a unique, innovative technology called VialVision™ (patent pending) that is able to reliably identify liquid levels, differentiate between multiple aqueous layers within a vial and then calculate their associated volumes.
Additional capabilities of the AutoMate-Q40:
Enable you to achieve improved precision and accuracy for the QuEChERS sample preparation methods being conducted
Ability to add sample capacity to your lab without adding staff or paying overtime
Reduce the negative impact that your lab operation currently has on the environment
Improve workplace safety

“Performance Evaluation of an Auotmated QuEChERS Workflow Platform for Analysis of Pesticides in Fresh Produce”
The Teledyne Tekmar AutoMate Q-40 is a robotic system designed to optimize and automate the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) sample preparation workflow. The performance of this system was evaluated in comparison to a manual sample preparation workflow using the AOAC 2007.01 unbuffered QuEChERS methodology where all samples were analyzed using liquid chromatography – tandem mass spectrometry (LC-MS/MS). Matrices used in this study were cabbage, valencia orange, raisin and purple corn flour. A Restek LC Multiresidue Standards Kit for Pesticide Analysis, Teledyne Tekmar QuEChERS extractions salts and C18/PSA dSPE cleanup and an ABSciex Qtrap 5500 mass spectrometer were also employed. LC parameters included the use of a Restek Ultra-Aqueous C18 Column (100 mm x 2.1 mm, 3 μm), 10 mM NH4HCO2 buffer (A: water, B: methanol) with 0.1% formic acid, 0.5 mL/min flow rate with 5 μL sample injection and MS/MS parameters were optimized individually. Results were determined for the instrument (limit of detection, limit of quantitation and linearity) and method (method detection limit, recoveries, relative standard error) and will be compared to determine the statistical differences (if any).
