Gooch Crucible with Sintered Disc

A Gooch crucible with Sintered Disc, was invented by Frank Austin Gooch hence it was name after him, is a filtration device for laboratory use (and was also called a Gooch filter. It is convenient for collecting a precipitate directly within the vessel in which it is to be dried, possibly ashed (a process of mineralization for preconcentration of trace substances prior to a chemical analysis, such as chromatography, or optical analysis, such as spectroscopy), and finally weighed in gravimetric analysis – which is 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.
