define gravimetric method of analysis|how to perform gravimetric analysis : online sales 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 quantities of the other constituents are known.

Method 925.10 in Official Methods of Analysis, 18th Edition (AOAC International, 2007) provides an approved method for determining the moisture content of flour. A preweighed sample is heated for one hour in a 130 o C oven and transferred to a desiccator while it cools to room temperature.
Gravimetric Analysis. Gravimetric analysis is a quantitative method in analytical chemistry wherein the concentration of a substance present in a sample is evaluated based on the measurement of its mass. This is done by precipitating the analyte (substance being analyzed) in a sample as a solid compound which is then separated, washed, dried and weighed.
Learn about gravimetric analysis, a method to determine the amount of a substance by measuring its mass.Gravimetric analysis is a technique through which the amount of an analyte (the ion being analyzed) can be determined through the measurement of mass. Gravimetric analyses depend on comparing the masses of two compounds containing the analyte. The principle behind gravimetric analysis is that the mass of an ion in a pure compound can be . In most cases the precipitate is the product of a simple metathesis reaction between the analyte and the precipitant; however, any reaction that generates a precipitate potentially can serve as a gravimetric method. Most precipitation gravimetric methods were developed in the nineteenth century, or earlier, often for the analysis of ores . What is gravimetric analysis – Definition. Gravimetric analysis or gravimetry refers to the quantitative determination of a chemical constituent using mass or weight measurements. The unknown chemical constituent (A) to be determined is converted into a substance of known composition (AB) by carrying out a chemical reaction.
Gravimetric analysis and volumetric analysis are two important methods in quantitative chemical analysis. While gravimetric analysis relies on the measurement of mass and the formation of a precipitate, volumetric analysis involves the measurement of volume and the reaction between the analyte and a standardized solution.
