the ability of measure very small auantites is called it

The ability to measure very small quantities is called "sensitivity". Sensitivity refers to the level of precision and accuracy in detecting or measuring tiny amounts or differences in a given parameter. To measure small quantities, specialized instruments and techniques are often employed. These can include sensitive balances, microscopes, spectrometers, or electrical devices designed to detect minute changes in voltage or current. Achieving high sensitivity typically involves minimizing background noise, maximizing signal-to-noise ratio, and employing advanced signal processing algorithms.
