The smallest amount of mass an analytical balance can detect is typically around 0.1 milligrams (100 micrograms). However, some high-precision analytical balances can detect even smaller masses, down to 0.01 milligrams (10 micrograms). The exact sensitivity depends on the specific model and calibration of the balance. It's essential to consider environmental factors like vibrations and air currents, which can affect measurement accuracy.

What are the advantages of analytical balance?
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.
What does weighing resolution of balance specify?
The weighing resolution of a balance specifies the smallest increment of weight that the balance can reliably measure and display. It indicates the precision of the balance, determining how finely it can detect changes in weight. A higher resolution means the balance can differentiate smaller weight differences, which is crucial for applications requiring accurate measurements. This specification is essential for ensuring the balance meets the needs of specific tasks, such as in scientific research or quality control.
What is Lassaigne's extract?
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?
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.
What is the perceptual threshold for vision?
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.
What is the smallest increase or increase in the intensity of a stimulus a person can detect?
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.

What is sensitivity in chemistry?
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.
What is the least count of lever balance?
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.
