That sample which consists of several portions.It may be pure or impure.It may be heterogeneous or homogeneous.
Analytical chemistry is concerned with investigation of the quantitative and/or qualitative characteristics of a given sample. For instance, an analytical chemist may qualitatively determine what the various polycyclic aromatic hydrocarbons in a tar sample are, and may also quantitatively analyze the concentrations of each species in the sample.
Methods of analytical chemistry are applicable.
This is not an obligatory procedure in all situations.
its a pattern that is analytical
mean of analytical model
Sample problems of Graphical and analytical methods are Vector addition and subtraction. These could be done in a analytical or graphical methodologies.
Simply because it may be some time before the sample arrives back at the lab. Furthermore, if you collect it in a container that is not adequate, you may introduce contamination on sampling. Decomposition may be an issue also, if stored incorrectly.

This branch of chemistry is called analytical chemistry.

place the sample on the microscope slide and observe it.
In geology say, a gross sample would be a representative sample of the whole rock. A lab sample would be a fraction of that, refined such that measurements are able to be made on a single mineral. for example, a piece of basalt would be a convenient field (gross) sample, from which say, mica is extracted after grinding and separation, to enable the 'date' of the basalt to be determined. Similar concepts would apply in other fields, such as biology, botany, water sampling and so on.
because it is the matrix in which circulating analytes reside
The purpose is to obtain a statistical representative sample from the material to be tested.
gross profit ratio
It is used every day by analytical scientist to find out the amount of substance in a sample.
