Further clean up of samples is easy with TELOS QuEChERS clean up kits. After initial sample prep with the extraction kit, a more advanced clean up is often required for the removal of interferences such as pigments, organic acids and fats. The removal of these interferences is carried out using a combination of three different SPE sorbents (see below).

TELOS PestiCarb: removes pigments, including chlorophyll and carotenoids
TELOS PSA: removes organic acids
TELOS C18: removes nonpolar interferences, including fats
