Screening and confirmation of psychotropic drugs in blood and urine by HPLC-LTQ Orbitrap MS / 法医学杂志

ABSTRACT

OBJECTIVE@#To establish a screening and confirmation method for psychotropic drugs and their metabolites in human blood and urine by HPLC-LTQ Orbitrap MS.@*METHODS@#The samples were pretreated with Sirocco protein precipitation plate, and then analyzed by HPLC-LTQ Orbitrap MS. The method was validated in terms of the limit of detection (LOD). An accurate mass database was created for psychotropic drugs screening.@*RESULTS@#The LOD for most of 56 determined compounds was < or = 0.1 ng/mL. The accurate mass database included the accurate mass information of 61 psychotropic drugs.@*CONCLUSION@#The method is accurate, rapid, sensitive and the database is suitable for psychotropic drugs screening and confirmation.
