- In analytical chemistry, gravimetric analysis is a method for quantitative chemical
analysis in which the substance to be estimated is converted to a
substance which can be separated pure and entire, and which is then weighed.
Commonly a highly insoluble precipitate is formed, filtered off, washed,
and dried (see dehydration). The weight
of substance sought is calculated from the weight and composition of the
- In geophysics, gravimetric analysis is the study of Earth's gravitational
field in a particular area. Small variations in the field can be caused
by the density of the rocks beneath the surface and can provide information
about structures that are otherwise inaccessible. The instrument used
for such a survey is known as a gravimeter.
