Automated QuEChERS Analysis For Food, Environmental, And Agricultural Laboratories

What is an Automated QuEChERS Analyzer?

An automated QuEChERS analyzer is a laboratory instrument used to automate sample preparation for pesticide and contaminant analysis. It performs extraction and dispersive solid-phase cleanup steps, preparing samples for GC-MS or LC-MS/MS analysis in food, environmental, and agricultural testing laboratories.

What is it used for?

It is used to prepare samples for multi-residue analysis by extracting pesticides, herbicides, mycotoxins, and other contaminants from complex matrices such as food, soil, and plant materials.

Why is QuEChERS used in analysis?

QuEChERS is used because it simplifies sample preparation while maintaining consistent extraction efficiency. It supports multi-residue detection across different matrices and is widely applied in regulatory and routine laboratory workflows.

How does an Automated QuEChERS Analyzer work?

It automates solvent extraction and cleanup steps in the QuEChERS method, reducing manual handling and improving consistency.

Process overview:

• Sample is placed in an extraction tube

• Solvent (acetonitrile) is added

• Salts induce phase separation

• Automated mixing extracts analytes

• Cleanup is performed using dSPE sorbents

• Extract is prepared for GC-MS or LC-MS/MS

Where is it used?

• Food safety laboratories

• Agricultural testing facilities

• Environmental analysis labs

• Cannabis testing laboratories

• Regulatory and research institutions

Key Technical Capabilities

• Programmable extraction workflows

• Automated solvent dispensing

• Controlled mixing and agitation

• Dispersive SPE cleanup automation

• Multi-sample batch processing

• Compatibility with standard QuEChERS kits

Typical Operating Parameters

When should you use an Automated QuEChERS Analyzer?

It should be used when laboratories require consistent sample preparation, higher throughput, and reduced manual variability, especially in regulated environments performing routine pesticide residue analysis.

Automated vs Manual QuEChERS

Which is better?

Automated QuEChERS improves consistency and throughput, while manual methods are suitable for low sample volumes or method development.

QuEChERS vs Solid-Phase Extraction 

What is the difference?

QuEChERS is used for multi-residue screening across complex matrices, while SPE is used for targeted cleanup and higher selectivity in specific analyses.
