Classifications of Analysis According to Sample


This is my first ever chemistry homework. A-Chem groupmates, sorry, this is the only thing I've got. =[

The classification of quantitative analysis may be based upon the size of the sample to be used for the analysis. An ultramicro analysis involves a sample whose size verges on that of a microgram (1 µg = 1 × 10-6 g). An analysis performed on a sample whose size ranges from 1 to 10 milligrams is called a micro analysis. A semimicro analysis deals with a sample weighing from 10 to 100 milligrams. Lastly, when the sample available weighs more than 0.1 grams, the analysis is classified as a macro analysis. 

kudos to this?
