This is clean-up tube is used for the extract from step 1 in QUECHERS AOAC Method 2007.01. QUECHERS (pronounced catchers) methods are used for multi-pesticide residue analyses in food . This is a 100 pack of tubes containing the d-SPE components.
Depend on the DisQuE 150 mg MgSO4 & 50 mg PSA to deliver a simple and straightforward sample preparation technique that is well suited to the multi-residue analysis for pesticides, veterinary drugs, and mycotoxins, across a variety of food and agricultural products. The product listed here is a clean-up tube that is used for the extract from step 1 in QUECHERS AOAC Method 2007.01. This listing contains a 100 pack of tubes containing the d-SPE components. The high-quality DisQuE 150 mg MgSO4 & 50 mg PSA sample preparation and extraction lab equipment comes with a conveniently packaged foil pouch and centrifuge tube.
Waters has developed an improved system of extraction to extract pesticides from fruits and vegetables, in order to overcome the deficiencies of traditional methods. The benefits of this advanced method are available in the DisQuE 150 mg MgSO4 & 50 mg PSA. In addition to time and effort saving, the lab equipment makes it possible to directly analyze the final extract by either GC-MS or by LC-MS/MS technology with a simple dilution.
The QUECHERS extraction that the DisQuE 150 mg MgSO4 & 50 mg PSA utilizes, is well suited for the multi-residue pesticide analysis of fruits and vegetables with high water content. For the analysis of products with low water content, additional water is added to optimize the extraction.

Before pulverization by a food chopper, blender, or another similar device, the sample is coarsely cut. The sample size (10–15 g) used in the DisQuE procedure is reduced compared with the traditional extraction procedures. It is important to ensure that the original sample is thoroughly homogenized. Blending the sample until it reaches a consistent texture reduces the variation in the sub-sample that will be used for testing and ensures better extraction efficiency. It is recommended that during the homogenization process, the use of cryogenic blending devices, liquid nitrogen, or dry ice is used to reduce the loss of highly volatile or thermally-labile pesticides.
