However, many real-world samples commonly encountered by law enforce- ment professionals are colored by impurities from crude synthetic pro- cesses, or from intentionally added pig- ments and dyes such as those found in household products, including fuel oil and antifreeze. Handheld Raman devic- es that utilize a more acute excitation lasers can overcome this limitation. Less contact, more control It is also critical to protect evidence from contamination if a sample is Circle 29 on Reader Service Card to successfully make it to court. As mentioned earlier, handheld Raman can perform analysis through packaging materials such as polymer bags, glass bottles, flasks and vials, allowing the user to screen materials by non-contact, non-destructive analysis, and without needing to open containers and risk contamination. Border checkpoints are a well- known hot spot for drug smuggling and officers often need access to rapid and reliable detection methods. In one case, Rigaku Analytical Devices' 1064nm handheld Raman, Progeny ResQ, identified illegal substances through wrapping and lubricant found inside a known drug mule. This would not have been possible using other methods of detection and demon- strates the value of this technique. Things to consider When it's time to research a handheld analytical device for investigative pur- poses, the following features are worth a look. First, the integrity of evidence is essential. Does the product have a feature (such as an integrated digital camera) that enables users to easily store sample evidence for use in the court- room? And how about ease of use? Can the device be used by an untrained oper- ator who will receive the same results as a PhD level chemist? By allowing users to perform confirmatory analysis upon arrest and provide substantial, proven evidence, cases can proceed to court much faster. This reduces backlog and increases the success rate of removing dangerous substances from circulation. Another thing to consider is the number of substances a handheld Print. Online. Mobile.
