Matrix-matched standards in the liquid chromatography–mass spectrometry determination of neonicotinoids in soil and sediment

The use of matrix-matched standards with a solid-liquid extraction and salting out without the addition of further cleanup steps or costly cleanup procedures associated with the quick, easy, cheap, effective, robust, and safe (QuEChERS) method was evaluated to address variations in ionization efficiency in the LC–MS/MS determination of neonicotinoid pesticides in complex environmental samples. Limits of detection (1.4–3.4 ng/g) and limits of...
