Quechers

Qcleanup®, salts and dispersive SPE products for QuEChERS treatment.

QuEChERS is a sample pretreatment initially developed by Michelangelo Anastassiades and Steven Lehotay mainly used for the analysis of multiple pesticides into fruits and vegetables. It is the acronym of Quick, Easy, Cheap, Effective, Rugged ans Safe. Three main methods are currently used the original method, the European standardized method EN 15662 and the AOAC official method 2007.01. Each method required an extraction process with salts and a clean-up process with SPE cartridges or by dispersive SPE.

AFFINISEP supplies all products required to carry out QuEChERS according to AOAC or CEN including dispersive SPE products or SPE cartridges.

Qcleanup® products for dispersive SPE are mixtures of powder in 2mL or 15mL centrifugation tubes for main scenarios encountered during pesticide analyses. This mixture contains a combination of magnesium sulfate anhydrous (MgSO4), primary secondary amine (PSA), carbon black (CB) or C18.
