TL;DR: This study highlights the fact that simple physical descriptions coupled with active drug content do not in themselves fully characterize the nature of the seized materials and the potential benefits of obtaining highly detailed spectra can indeed translate into information that is not readily available from other methods but would be useful for tracing of drug distribution networks.

TL;DR: By using far-red (785 nm) excitation the level of fluorescence background even in untreated seized samples is sufficiently low that there is little difficulty in obtaining good quality data with moderate 2 min data accumulation times, and the simple nature of the measurements lends itself to automatic sample handling so that sample throughputs of 20 samples per hour can be achieved with no real difficulty.

TL;DR: The fact that there are many examples of batches of tablets in which the differences between each set are sufficiently small that they appear to arise only from random variations within a standard manufacturing method implies that, with more extensive data, it may be possible to recognize the "signature" of tablets prepared by major manufacturers.

TL;DR: In this paper, a comparison of argon-cooled and nitrogencooled systems under strictly optimised conditions where possible, and on one spectrometer, is made, and the effects of the nebulisation system on the optimisation and on the results are discussed.

TL;DR: Forensic issues around enforcement decisions following laboratory results for non-compliant consignments containing nitrofurans are summarised herein, including those that have been referred for technical appeal to the UK Government Chemist.
