One example of the gravimetric methods is to measure the weight of a porcelain dish where as much . as 0,50 g of a sample that has been heated in an oven at temperature of 110-120 for 2 hours, .
Gravity surveys are geophysical techniques used to measure the variations in the Earth's gravitational field at different locations. These surveys involve the measurement of the gravitational acceleration at the Earth's surface, typically expressed in terms of milligals (mGal) or microgals (μGal). The purpose of gravity surveys is to map and understand the distribution of .The publication in 1540 of Vannoccio Biringuccio’s Pirotechnia is an early example of applying gravimetry—although not yet known by this name—to the analysis of metals and ores. 1 Although gravimetry no longer is the most important analytical method, it continues to find use in specialized applications.

The processing and cleansing of gravimetric data are explained for their applicability in explorative practice. . Nonetheless, many other applications can be listed (see, e.g., Reynolds , Valenta ). In brief, gravity is an indicator of any form . Quantitative Applications. Unlike precipitation gravimetry, which rarely is used as a standard method of analysis, volatilization gravimetric methods continue to play an important role in chemical analysis. Several important examples are discussed below.
In most methods the precipitate is the product of a simple metathesis reaction between the analyte and the precipitant; however, any reaction generating a precipitate can potentially serve as a gravimetric method. Most precipitation gravimetric methods were developed in the nineteenth century, or earlier, often for the analysis of ores. Figure .
