This unique disciplinary historical past of the sector of diplomacy examines its early emergence within the mid-nineteenth century to the interval starting with the outbreak of worldwide conflict II.

However, the more recent UNODC data indicate a higher morphine content in raw opium from Afghanistan. Because of this and/or increased laboratory efficiency, a higher yield reportedly can be achieved, with a conversion ratio of between 7:l and 6:l . For the above reasons, in the manufacture process documented, no measurement of the yield of heroin base could be made to compare with the data provided by UNODC. The materials were weighed on location using a beam balance and weights that CNPA had borrowed from a local trader.
The extraction of morphine base during the process observed by the authors was based, for the most part, on the Thiboumery and Mohr method. Unlike in the production process mentioned above, the morphine base was not purified with charcoal. That first purification step was carried out at the stage of the heroin base, that is, after the morphine had been converted to heroin. In this process, only a very small quantity of organic solvent was used, when the purified heroin base was transformed into heroin hydrochloride.
Impurity profile of a l-phenyl-2-propanone sample, obtained through gas chromatographylmass spectrometry The repeatability of the method was assessed on the basis of 10 analyses of one randomly selected P-2-Psample. All tests were performed on the same day. The standard deviation and relative standard deviation were calculated for retention times and peak areas of two selected peaks, the internal standard (diphenylamine) and phenylacetic acid. The results obtained are presented in table 1. 28 The reproducibility of the method was determined in 30 analyses of various randomly selected P-2-Psamples.
