What is Gravimetric Analysis? Gravimetric analysis is a method in analytical chemistry to determine the quantity of analyte based on the mass of a solid. Example: Measuring the solids suspended in the water sample – Once a known volume of water is filtered, the collected solids are weighed.
Gravimetric analysis samples require filters to be weighed both before and after sampling to determine the amount of contaminate collected. Zefon preweighed cassettes eliminate the inconvenience of preweighing the filters by providing cassettes preloaded with a PVC filter weighed to within 0.00001g (10µg).
