μSPE Clean-up Tool for TriPlus™ RSH and TriPlus RSH SMART Autosamplers

Helping laboratories achieve reliable and high-throughput GC-MS analysis of pesticides, the automated cartridge-based micro Solid Phase Extraction (μSPE) Clean-up Tool for QuEChERS extracts is available for the TriPlus™ RSH and TriPlus RSH SMART Autosamplers. This tool offers a fully automated on-line approach for clean-up of QuEChERS extracts, and replaces the dispersive SPE manual procedure. Suitable for a wide variety of food matrices, even those with high lipid contents, the μSPE tool offers a unified method for GC-MS analysis of hundreds of pesticides and organic contaminants. By using a single type of miniaturized cartridge, this tool also offers the benefits of scaling down sample volume and solvent usage.

Enhancing the automated workflow capability of the TriPlus RSH and TriPlus RSH SMART autosamplers, the μSPE Clean-up Tool for QuEChERS extracts provides today's analytical testing laboratories with the productivity they need to succeed. Unlike classic vacuum manifold-based SPE, the flow rates applied to the μSPE cartridge can be precisely controlled with a liquid syringe by the autosampler, assuring optimum recovery. Low-flow rates of ∼2 μL/s in the load and elution steps are used for sharp analyte/matrix separation.

Other advantages of the μSPE Clean-up Tool include the following:

• Unified clean-up method for all food matrices due to one cartridge type, complete with optimized sorbent bed materials.
• No concentration step thanks to miniaturization at the microliter scale, eliminating routine dilution during the SPE elution step.
• Cleaner extracts due to higher selectivity, resulting in extended instrument uptime.
• Green chemistry as a result of highly reduced solvent consumption.
• Cycle time optimization as preparation of the next sample is performed in parallel with the current chromatographic run, enabling an economical workflow.
• SMART technology enabled when used with the TriPlus RSH SMART autosampler and SMART syringes, for safer and traceable operations.
