Automated Micro Solid Phase Extraction (SPE) Products

Automated micro Solid-Phase extraction (μSPE) products
Achieve reliable and high-throughput analysis by automating cleanup of QuEChERS extracts using the cartridge based Thermo Scientific micro Solid-Phase extraction (SPE) products. The QuEChERS sample preparation method is used to extract pesticides and organic contaminants from
food matrices with subsequent analysis by GC or liquid chromatography-mass spectrometry (LC-MS). This μSPE capability, which is available for the Thermo Scientific TriPlusTM RSH Autosampler and LC systems.

Comments

Replaces the manual dispersive SPE (dSPE) procedure
Enables reliable and high-throughput extract cleanup
Is suitable for a wide variety of food matrices, even those with high
lipid contents
Offers a unified method for GC or LC-MS analysis of hundreds of pesticides and organic contaminants
Enables scale down of sample volume and solvent usage
Application note: Multi-pesticide residues analyses of QuEChERS extracts using an automated online μSPE clean-up coupled to LC-MS/MS

What is the purpose of the chemicals?

• MgSO: removes residual water, and induces phase separation between water content in sample and acetonitrile layer
• NaCI: removes residual water, and induces phase separation between water content in sample and acetonitrile layer
• NaOAc: buffers the sample to stabilize pH
• Disodium hydrogencitrate sesquihydrate: buffers the sample to stabilize pH
 .Trisodium citrate dihydrate: buffers the sample to stabilize pH • PSA: removes free fatty acids and other acidic co-extractives
• C18: removes fats, sterols, and other non-polar interferences from sample
 .GCB: removes pigment (not recommended for use with planar pesticides)
