Spectrophotometry
Spectrophotometry is a common laboratory method used to measure how much light passes through a sample, like a liquid or solution. It's similar to how sunglasses block certain amounts of light - but in a precise, scientific way. Lab technicians and scientists use this technique to figure out things like the concentration of substances in samples or to check the quality of products. It's a fundamental skill in many laboratories, especially in fields like chemistry, biology, environmental testing, and quality control. When you see this on a resume, it means the person knows how to operate laboratory instruments called spectrophotometers and can perform accurate measurements.
