%ME was defined by the following equation where A is the peak area of the standard solution dissolved in acetonitrile, B is the peak area of the standard solution dissolved in blank egg matrix (Choi et al., 2015). If ME% falls into the scope of –20 to 20, it indicates no ME; ME%<−20 indicates ion suppression; ME%>20 indicates a signal enhancement.
