分析说明
An rapid method for the simultaneous determination of the Z-drugs or sleep aids: zopiclone, zolpidem, and zaleplon is presented here. The need for greater analytical capacity and throughput for the analysis of sleep aid medicines (Z-drugs) in forensic toxicology laboratories can be met by the use of fast Ascentis Express 2.0 micron Fused Core UHPLC Columns.
