An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
Though short-beam balances were in use before 1866, Bunge was the first engineer to document a theory for their operation and started manufacturing the balances in Hamburg. [3] It was Florenz Sartorius who from 1870 started the mass production of the scientific balances in his business in Göttingen. [4]
When using the triple beam balance, it is recommended that one start with the lowest level of precision (e.g 100 gram increments). For example, if an object weighs 327 grams, the 100 gram pointer will drop below the fixed mark on the 4th notch (400g); it will then need to be moved back to the third notch (300g).

A microbalance is an instrument capable of making precise measurements of weight of objects of relatively small mass: of the order of a million parts of a gram.In comparison, a standard analytical balance is 100 times less sensitive; i.e. it is limited in precision to 0.1 milligrams.
