Nettet12. feb. 2024 · Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength. NettetGenerally speaking, sampling is a statistical means of measuring a given population with the intent to accurately extend the measurement to represent a larger population. But just like measurement, not all sampling methods are created equal. Sampling methods typically fall into one of two categories: probability- and non-probability-based.
