Bruker Daltonics
For the detection of drugs a couple of quick tests are avail-able which were used by the police departments and the State Offices of Criminal Investigations. These tests are limited to substance specific reactions and do not give any information about different drug compositions (thin down compounds, by-products, precursors, impurities etc.) which were necessary for criminal investigations. For a clear identification of complex mixtures GC/MS is still the method of choice. With the mobile GC/MS system E²M a fast and inexpensive detection and identification of drugs can be accomplished directly at the scene of crime. This application note demonstrates the time saving determination of differ-ent drugs/drug compositions with the E²M in the GC mode and by direct measurements with the Air/Surface probe.
Sampling preparation
For this application note the following solutions were pre-pared by dissolving the raw material in methanol (hashish: 4.7 mg/ml, marihuana: 2.2 mg/ml, morphine: 2.8 mg/ml, cocaine: 2.2 mg/ml, heroin: 2.6 mg/ml). For the identifica-tion on-site (not quantification) where a microbalance may not be present this can be done by transferring the amount of one micro-spatula tip (1 – 5 mg) into a vial filled with 1 ml methanol.

Conclusions
With the mobile GC/MS system E²M drugs (here: hashish, marihuana, morphine, cocaine, heroin) can be identified directly on the scene of crime within 10 – 15 min. The operation of the system is reduced to the lowest possible level so that non-chemists are able to run the system. In comparison to classical investigations (laboratory measurements), which are time consuming, and expensive identification of drugs can be carried out quickly and at low cost. Therefore the GC/MS system E²M is a powerful analytical tool to save time and money.
