Gravimetric analysis - Wikipedia

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 …

Difference Between Volumetric And Gravimetric Coal Feeder

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.


2. Sampling Sampling for Solids Analysis. Suspended solids present a special sampling problem. In order to avoid unrepresentative sampling or particle break-up, it is important that: (1) the fluid stream to be sampled is completely mixed at the point of sampling; and (2) the disturbance of the flow pattern of this stream is minimized, especially at the mouth of the sampling device.
