Mass Spec
Mass Spec (short for Mass Spectrometry) is a widely used testing method in laboratories that helps identify what substances are made of. Think of it like a very advanced scale that can tell exactly what chemicals are in a sample and how much of each is present. Scientists and lab technicians use this tool to test medicines, check food safety, analyze environmental samples, or ensure product quality. It's an essential skill in pharmaceutical, biotechnology, and testing laboratories. When you see this term in a resume, it usually means the person has experience operating these sophisticated instruments and analyzing the results they produce.
