Sep Sci plus 2018, 1 , 296–305 DOI: 10.1002/sscp.201700009 The cover picture shows a novel method using dispersive solid‐phase extraction combined with UHPLC‐MS/MS for determination of seven pesticide residues in soil samples. The analytes were first extracted from the soil samples into acetonitrile, and the ultrasound technique was applied to increase the extraction efficiency. Next, a dispersive solid‐phase extraction purification step was performed by directly adding adsorbents (PSA, C18, GCB and MgSO4) into the extraction solution. All analytes were successfully separated within 4 min, and the method showed good sensitivity and specificity.
