|
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 |
|
|
volatilization gravimetry |
the analyte is separated from other constituents of a sample by converting it to a gas of known chemical composition. |
|
|
electrogravimetry |
the analyte is separated by deposition on an electrode by an electrical current. |
|
|
gravimetric titrimetry |
the mass of a reagent of known concentration required to react completely with the analyte provides the information needed to determine the analyte concentration. |
|
|
Atomic mass spectrometry |
uses a mass spectrometer to separate the gas- eous ions formed from the elements making up a sample of matter. |
|
|
Gravimetric methods |
are quantitative methods that are based on determining the mass of a pure compound to which the analyte is chemically related. |
|
|
analytical balance |
Gravimetric methods of analysis are based on mass measurements with an _______, an instrument that yields highly accurate and precise data. |
