Cyanoacrylate fuming (aka CA fuming or superglue fuming) is widely recognized as a powerful and useful process for the visualization of latent fingerprints on many types of surfaces. Almost nothing in the forensic sciences, however, is less standardized. What is considered standard practice in one laboratory may be a prohibited practice in another. Equipment can range from rudimentary containers to highly sophisticated laboratory cabinets. Results are often varied and erratic and there seems to be no correlation to expense.
To achieve optimum results in latent print development using the CA process, it is first necessary to identify and understand the variables involved. The evolution of the different cyanoacrylates, now manufactured specifically for latent print development, as well as the introductions of a wide variety of fuming chambers, have induced a false belief that one only needs to push the “Start” button in order to achieve the best possible results.
It is imperative that users understand the process of polymerization and know that the variables involved must be understood and addressed. Unfortunately, many technicians adopt the same unwarranted faith in the “automatic” settings for CA chambers with predictably mediocre results. This workshop will take you through processes and procedures to ensure that you are fuming at your best.
