The instrument used in ultraviolet–visible spectroscopy is called a UV/Vis spectrophotometer. It measures the intensity of light after passing through a sample (), and compares it to the intensity of light before it passes through the sample (). The ratio is called the transmittance, and is usually expressed as a percentage (%T). The absorbance, , is based on the transmittance: WebSpectrometers are one of the most ubiquitous tools in most labs because an enormous amount of information about a substance can be gleaned from how it …
