The upper natural layer was transferred into a clean up examination tube and eva-porated to dryness beneath a mild stream of nitrogen inside of a forty °C dry bath. The samples had been reconstituted with 100 μL of cell phase and positioned in car-sampler vials for Investigation.
In the other deadly scenarios, mephedrone was discovered in combination with other medicine, therefore it really is hard to explain the precise part that mephedrone performed from the documented fatalities.
