Instrumental studies refer to research that focuses on the development and application of instruments used for measurement and analysis in various fields. These studies often involve the design, calibration, and validation of tools that can accurately collect data, such as spectrometers, chromatographs, or survey instruments. The goal of instrumental studies is to enhance the reliability and precision of measurements, which can lead to better decision-making in areas like environmental science, healthcare, and engineering. By improving these instruments, researchers can obtain more accurate results, ultimately contributing to advancements in technology and science.
