Analytical instruments are tools used to measure and analyze the properties of substances. They help scientists and researchers understand the composition, structure, and behavior of materials. Common examples include spectrometers, which measure light absorption, and chromatographs, which separate mixtures into their individual components. These instruments are essential in various fields, including chemistry, biology, and environmental science. They provide accurate data that can lead to discoveries, quality control in manufacturing, and safety assessments in food and pharmaceuticals. By using analytical instruments, professionals can make informed decisions based on precise measurements.
