Migration of N,N-Bis(2-hydroxyethyl) alkyl(C8-C18)amines from five various polypropylene capsules to Tenax® and coffee dust were studied. Just one step extraction-cleanup process using salting out liquid-liquid removal (SALLE) technique accompanied by ultra-high performance fluid chromatography-tandem size spectrometry (UHPLC-MS/MS) ended up being applied. The crucial parameters on the SALLE procedure such extracting solvent, extracting amount, sampl
