Determination of Aconitine in Body Fluids by LC/MS/MS

15 May 2012

This note describes a rapid and sensitive method for the quantification of aconitine in biological specimens. The method involves SPE purification prior to analysis using LC/MRM. The utility of the method was demonstrated by its application to authentic samples in 2 fatal cases of suspected aconitine poisoning.

Alliance® HPLC - e2695 Separations Module

Waters

The Waters Alliance 2695 Separations Module is a high performance liquid chromatographic system with a quaternary, low-pressure mixing pump and inline vacuum degassing. Flow rates from 50 uL/min to 5 mL/min can be generated for use with 2.1 mm ID columns and larger. The autosampler has a maximum capacity of 120 vials (12x32, 2-mL) with programmable temperature control from 4 to 40°C. A heated column compartment provides temperatures from 5 degrees above ambient to 65°C. The detector is a photodiode array (model 2996) with a wavelength range of 190-800 nm and sensitivity settings from 0.0001-2.0000 absorbance units. All components of the HPLC are controlled through Waters Empower software.
