An analytical balance is typically defined as a balance with a display resolution of 0.1mg. Usually it will have a draft shield around it. Although it can be used to describe any precision balance.
Lassaigne test is a method in qualitative analytical chemistry used to detect halogens, sulfur or nitrogen in organic compounds.
The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.
The nose can detect an odor from the presence of only a few molecules of substance.
The absolute threshold is the smallest amount of light that a person can detect. The human absolute threshold we can detect is a candle flame at 30 miles away.
The smallest increase in the intensity of a stimulus that a person can detect is called the just noticeable difference (JND). This is the minimum amount by which two stimuli must differ in order for the difference to be perceptible to an individual.

A sensitivity balance in science refers to an instrument or device that is used to measure minute changes in weight or mass. It is designed to be highly sensitive in detecting even the smallest variations, making it ideal for precise measurements in research and experimentation.

Sensitivity in chemistry refers to the ability of an analytical method to detect small changes in concentration of a substance. A more sensitive method can detect lower concentrations of analytes. Sensitivity is often expressed as the limit of detection or the limit of quantitation of an analytical method.
The least count of a lever balance is the smallest measurement that can be accurately read or measured using the device. It is determined by the precision of the markings on the scale or the smallest division that can be observed on the balance. The least count is crucial for obtaining accurate measurements and is typically expressed in units such as grams or millimeters depending on the scale being used.
