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 .Gravimetric methods: The . quantitative methods. that are based on determining the . mass. of a . pure compound . to which the . analyte. is . chemically related. • Precipitation gravimetry: The . analyte. is separated from a solution of the sample as a . precipitate. and is converted to a compound of known composition that can be weighed . This document discusses gravimetric analysis methods which involve weighing precipitates or volatile decomposition products. It describes two major types - precipitation methods where the analyte is converted to a precipitate, and volatilization methods where the analyte or its products are vaporized.Gravimetric Analysis 9/17/13 page 6 The gravimetric method is one of the most accurate methods of analysis. It is usually applied when the analyte concentration exceeds 1%. One distinct advantage is that no standard is required. However, precipitations may not be very specific (you may
3. Thermogravimetric analysis(TGA) • Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. • This measurement provides information about physical phenomena, such as phase transitions, absorption and desorption as well as .

analytical method in the early eighteenth century. Titrimetric methods were not well received by the analytical chemists of that era because they could not duplicate the accuracy and precision of a gravimetric analysis. Not surprisingly, few standard texts from the 1700s and 1800s include titrimetric methods of analysis.
Because the release of a volatile species is an essential part of these methods, we classify them collectively as volatilization gravimetric methods of analysis. 8.4: Particulate Gravimetry Precipitation and volatilization gravimetric methods require that the analyte, or some other species in the sample, participates in a chemical reaction.
