Calibration sensitivity refers to the ability of an instrument to accurately detect changes in levels of a sample. Analytical sensitivity refers to the lowest amount of analyte that can be reliably measured by an assay. Calibration sensitivity is related to instrument performance, while analytical sensitivity is specifically related to the assay's detection limit.
Sensitivity describes the smallest change an instrument can detect. Range describes the largest change an instrument can detect.
The sensitivity of a thermometer depends on the scale or division of measurement on its display. Thermometers with smaller divisions or scales have higher sensitivity as they can detect smaller changes in temperature. Additionally, the design and materials of the thermometer can also impact its sensitivity.
The difference threshold, also known as the just noticeable difference, is the smallest change in a stimulus that can be detected by an observer. It is a measure of the sensitivity of a human's sensory system to changes in stimuli.
Calibration involves comparing the output of a device to a known standard to ensure accuracy. Measurement is the process of quantifying a physical quantity, such as length, weight, or temperature. Calibration helps ensure that measurements are accurate and reliable.
Using the same balance ensures consistency and accuracy in the measurements. It eliminates potential errors that could arise from differences in calibration or sensitivity between different balances. This helps to improve the reliability and reproducibility of the mass determinations.
