As new “bath salt” drugs such as methylone, ethylone, mephedrone, butylone and other methcathinone analogs increase in popularity, toxicologists require native and labeled certified reference materials to accurately identify and quantify the new compounds in patient samples.
The combination of ion-exchange SPE with the HILIC HPLC separation provides a novel approach for the testing of problematic bath salt compounds.
LC-MS/MS is a powerful tool that brings numerous benefits to the clinical sample analysis arena. However, due to the complexity of the instrumentation there are some unique challenges that also accompany these benefits. Even following sample extraction and cleanup, matrix effects from the samples can cause interferences or impact ionization efficiency.
