“…The concentration range of LODs for PCPCs was 2.82-36.36 pg mL À1 and of LOQs was 9.39-121.08 pg mL À1 . The LODs and LOQs obtained by this method were similar to those reported in other studies using traditional extraction techniques combined with UHPLC-MS/MS, such as LLE-UHPLC-MS/MS47 and SPE-UHPLC-MS/MS 26,48. In general, the T A B L E 1 acid; DLLE, dispersive liquid-liquid extraction; EtP, ethylparaben; LLE, liquid-liquid extraction; LOD, limit of detection; LOQ, limit of quantitation; MeP, methylparaben; OH-EtP, ethyl protocatechuate; PrP, propylparaben; TCC, triclocarban; TCS, triclosan.…”
