Perkin Elmer is a global leader in providing instruments that improve environmental and human health studies. I studied the user flow and usability of one of their large machines for the next iteration of mass spectrometers. My study found that users often place samples, and sometimes beverages, on the machine during testing, which is typically forbidden behavior. Samples could easily be contaminated and ruin hours of work. That’s why I helped develop a machine that not only had a clear flow of use, but also flowing and sloped surfaces that prevent items from being placed on it.
