With all due respect to Dr. Drummer and his research involving multiple drug forensic identifications with a single injection, which I respect as to the methodology being expanded, I have a serious concern as to the multiple "forensic identifications" of multiple drugs or controlled substances with a single injection. While I will concede that the data can be collected, it has always (and hopefully will always be) a mainstay in forensic analysis the 2 chemically different methods must be used to make a forensic identification of controlled substances-- one to identify and one to confirm. I know it can be argued that RT or RI is different from mass spectra as to the chemistry involved, but was a drug identified that was not in the sample but due to carry-over contamination or other contamination? Sometimes speed must give way to the old
protocols dating back to wet chemistry in the early days of chemistry--one must confirm a result using two chemistries from two different samples. I will concede that an indication can be made, but I resist the idea that a forensic identification is made with this type of analysis.
I await your responses.
Thank you
