Quechers and Passthrough SPE columns
Solutions based on solid phase to remove interferences compounds via a simple method
Quechers extraction salts & dispersive SPE
Passthrough SPE columns
Several solutions exist to quickly remove some interference in a very short time.
QuEChERS is a sample pretreatment mainly used for the analysis of multiple pesticides into fruits and vegetables. It is the acronym of Quick, Easy, Cheap, Effective, Rugged ans Safe.
They are mainly used in centrifuge tubes
Passthrough SPE columns are another way to roughly remove interferences. In a SPE column, a powder sorbent will interact with some interferences when the sample passes through the SPE column. This one-step process is much shorter than usual 3-steps SPE process.
